• Public static PAT in Nat/Global conflicts

  I seem to have a problem because of a conflict between the static PAT and nat/global pool.

  I have a config with the following static and ACL. (192.169.10.2 and 192.168.10.3 are two address on the same adapter on the same server)

  static (dmz, outside) tcp 212.xx.xx.4 www 192.168.10.2 5080 netmask 255.255.255.255 0 0

  static (dmz, external) 212.xx.xx.5 192.168.10.3 netmask 255.255.255.255 0 0

  line 100 access list 7 permit tcp any host 212.xx.xx.4 eq www

  100-list access line 8 permit tcp any host

  212.XX.XX.5 eq ftp

  line 9 of the access list 100 permit tcp any host 212.xx.xx.5 eq ftp - data

  With this new configuration when I issued the "cl" xlate I outwardly use the site and the FTP site.

  However, as soon as the (192.6.12.2/3) server to connect to the internet the static PAT stops working:

  static (dmz, outside) tcp 212.xx.xx.4 www 192.168.10.2 5080 netmask 255.255.255.255 0 0

  It is interesting the individual static (ftp) continues to work:

  If I do a "show xlate" he mentions a 'Global 212.xx.xx.22 192.168.10.2 Local. " That's probably why it does not work as it comes to take an address from the global pool and is no longer uses 212.xx.xx.4. I don't know why this conflict happens? Any help much appreciated.

• Static and dynamic NAT at the same time?

  Is this possible? Let's say you have 20 public address pool and you have 30 computers LAN. You want to assign the same public address for some of the servers. And the rest can get the addresses of the pool at random.

  It would be nice if we can easily do the appropriate firewall rules.

  Yes, it is possible, you can use nat and global commands for dynamic conversion and use the static commands for static translation at the same time.

  Here is an example:

  Public rate IP-range outdoors: xxx.xxx.xxx.0/27

  (IP addresses are xxx.xxx.xxx.1 - xxx.xxx.xxx.30)

  Private range of IP addresses on the inside: yyy.yyy.yyy.0/24

  In the example I'm going to static translate xxx.xxx.xxx.2 to yyy.yyy.yyy.2 Server1 (ditto for server2, but by using adresse.3)

  All other IP addresses is translated dynamics.

  Here is an example of how you can do this:

  IP address outside xxx.xxx.xxx.1 255.255.255.224

  IP address yyy.yyy.yyy.1 255.255.255.0 inside

  NAT (inside) 0 access-list sheep

  NAT (inside) 1 yyy.yyy.yyy.0 255.255.255.0

  Global 1 interface (outside)

  public static yyy.yyy.yyy.2 xxx.xxx.xxx.2 (indoor, outdoor)

  public static yyy.yyy.yyy.3 xxx.xxx.xxx.3 (indoor, outdoor)

  access-list deny ip host yyy.yyy.yyy.2 sheep all

  access-list deny ip host yyy.yyy.yyy.3 sheep all

  access-list sheep ip allow a whole

• Fusion 4 - static IP for NATted VM?

  You used to be able to browse to/Library/Application Support / VMware Fusion/vmnet8/dhcpd.conf and edit the file to always assign the same address to a given virtual machine.

  See this link for someone decent tutorial on how to do it: http://www.thirdbit.NET/articles/2008/03/04/DHCP-on-VMware-Fusion/

  The problem is, I can't seem to find these files in VMware Fusion 4. It is a function of trade mark or break for me.

  Now, of course this could also be solved in VMware Workstation with network... editor who miss me so much in Fusion, but it's a different problem.

  Any advice here?

  See the section: "/ Library/Preferences/VMware Fusion / '.

• Apart from the demilitarized zone or static NAT?

  Hello!

  I'm trying to implement the static translation from outside my network in DMZ. I tried with nat, global and static use but failed with both. The problem is that packets are go to the servers in the DMZ but nothing is returned to the sender. Also, when I try to access a Web server in DMZ I get SYN timeout.

  The traffic of my LAN (inside) local DMZ works as it should however.

  -Important conf--->

  access-list ON scope allowed any ip a

  Global interface (dmz) 12

  NAT (outside) - 12 OUT out access list

  Access-group OUT in the interface outside

  -more than information--->

  Interior - the security of IP 10.0.13.1 level 100

  DMZ - security level 50, IP 172.16.13.1

  outer - level 0, the security of IP 192.168.13.2

  Bastionhost = Web server

  -See the nat--->

  match any ip outside any demilitarized zone

  dynamic translation to the pool of 12 (172.16.13.1 [Interface PAT])

  When I used static instead of nat, overall I had so many untranslate_hits I sent to servers in DMZ.

  Thank you.

  Your following config is fine, your bastionhost here with a public IP address of mapping that will allow the access server to the internet as well.

  allowed any icmp extended WEB access list a--> add this option to test accessibility outside bastionhost / internet and remove it later.

  IP any host 192.168.14.5-> or add 'eq www' to specify the port allow Access - list extended WEB.

  static (dmz, outside) tcp 192.168.14.5 www bastionhost www netmask 255.255.255.255

  group-access WEB interface outside

  You can omit the next part that meant allowing internet access only, bastionhost not allowing users to access.

  Global 1 192.168.14.5 (outside)

  NAT (dmz) 1 bastionhost 255.255.255.255

  BTW, what is the State of the road looks like?

• NAT 0 0 nat nat static ACLs

  Anyone know what the order of nat/static... .is it nat 0 acl, nat 0, static, nat? where nat 0 acl is first and nat is the last... for example if I have an address that meets the criteria of nat 0 acl, nat 0, static, NAT... what happens?

  John

  Order of preference for the translation goes as follows:

  (1) nat 0 access-list (free of nat)

  (2) match against existing xlates

  (3) static

  (a) nat public static with no access-list (first match)

  (b) public static pat with no access-list (first match)

  (4) nat

  (a) nat access-list (first match) Note: nat 0-list of access is not part of this command.

  (b) nat (best match) Note: when you choose a global address of multiple pools with the same id of nat, the following order is tried

  (i) if the id is 0, create an xlate identity.

  (II) use the global pool for dynamic NAT

  (III) use the global pool for PAT dynamic

  (5) error

• Public static political static NAT in conflict with NAT VPN

  I have a situation where I need to create a VPN site-to site between an ASA 5505 using IOS 7.2 and a Sonicwall NSA4500. The problem arises where the LAN behind the Cisco ASA has the same subnet an existing VPN currently created on the Sonicwall. Since the Sonicwall cannot have two VPN both run on the same subnet, the solution is to use policy NAT on the SAA as well as for the Sonicwall, the new VPN seems to have a different subnet.

  The current subnet behind the ASA is 192.168.10.0/24 (The Sonicwall already has a private network virtual created for another customer with the same subnet). I try to translate it to 192.168.24.0/24. The peer LAN (behind the Sonicwall) is 10.159.0.0/24. The ASA relevant configuration is:

  interface Vlan1

  IP 192.168.10.1 255.255.255.0

  access extensive list ip 192.168.24.0 outside_1_cryptomap allow 255.255.255.0 10.159.0.0 255.255.255.0

  list of access VPN extended permit ip 192.168.10.0 255.255.255.0 10.159.0.0 255.255.255.0

  public static 192.168.24.0 (inside, outside) - list of VPN access

  card crypto outside_map 1 match address outside_1_cryptomap

  In addition, there are other static NAT instructions and their associated ACLs that allow certain traffic through the firewall on the server, for example:

  public static tcp (indoor, outdoor) interface smtp SERVER smtp netmask 255.255.255.255

  The problem is this: when I enter the static strategy statement NAT, I get the message ' WARNING: real-address conflict with existing static "and then it refers to each of the static NAT statements reflecting the external address to the server. I've thought about it, and it seemed to me that the problem was that policy NAT statement must be the first statement of NAT (it is the last one) so that it is run first and all traffic destined to the VPN to the Sonicwall (destination 10.159.0.0/24) tunnel would be properly treated. If I left him as the last statement, then the other static NAT statements would prevent a part of the 10.159.0.0/24 network-bound traffic to be correctly routed through the VPN.

  So, I tried first to my stated policy NAT upward in the ASDM GUI interface. However, moving the declaration was not allowed. Then I tried to delete the five static NAT statements that point to the server (an example is above) and then recreate them, hoping that would then move up the policy statement NAT. This also failed.

  What Miss me?

  Hello

  I assumed that we could have changed the order of the 'static' , the original orders, but as it did not work for some reason any then it seems to me that you suggested or change, that I proposed should work.

  I guess that your purpose was to set up static political PAT for the VPN for some these services, then static PAT of public network access, then static NAT to policy for the rest of the network in-house.

  I guess you could choose any way seems best for you.

  Let me know if get you it working. I always find it strange that the original configuration did not work.

• On the Question of VPN S2S source NAT

  Currently we have a number of implementation of VPN with various clients.  We are NAT'ing range them at a 24 in our network to keep simple routing, but we seek to NAT Source our resources due to security problems.  It is an example of a current virtual private network that we have configured:

  outside_map crypto card 5 corresponds to the address SAMPLE_cryptomap

  outside_map 5 peer set 99.99.99.99 crypto card

  card crypto outside_map 5 set ikev1 transform-set ESP-3DES-MD5 SHA-ESP-3DES

  card crypto outside_map 5 the value reverse-road

  My question revolves around the Source NAT configuration.  If I understand correctly, I have to configure 3 statements of NAT per NAT Source since there are three different destinations that are NAT' ed.  I think I would need to add this:

  network of the SITE1_APP_JCAPS_Dev_VIP_NAT object

  Home 88.88.88.81

  network of the SITE1_APP_JCAPS_Prod_VIP_NAT object

  Home 88.88.88.82

  NAT (inside, outside) static source SITE1_APP_PACS_Primary SITE1_APP_PACS_Primary_NAT CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination

  Is that correct, or is at - it an easier way to do this without having to add all statements of NAT?  Moreover, any change would be to do on the access list?

  Hello

  To my knowledge you should not create several new instructions from NAT. You should be well just create a new Group 'object' for new addresses your source address NAT.

  To better explain, take a look at your current ' object-group ' that defines your source addresses

  the APP_CLIENT_Hosts object-group network

  network-object, object SITE1_APP_JCAPS_Dev_VIP

  network-object, object SITE1_APP_JCAPS_Prod_VIP

  network-object, object SITE2_APP_JCAPS_Dev_Host

  network-object, object SITE2_APP_JCAPS_Prod_VIP

  network-object, object SITE1_APP_PACS_Primary

  Now you can do this sets up a "object-group" that contains a NAT IP address for each of the IP addresses inside the ' object-group ' and 'object' used above. The IMPORTANT thing is that the ' object-group ' that contains the NAT IP addresses is in the SAME ORDER as the actual source addresses.

  I mean, this is the first IP address is in most object - group ' will correspond to the first IP address in the newly created "object-group" for the IP NAT addresses.

  As above, you can simply have the same "nat" configurations 3 as before but you change/add in the newly created "object-group"

  For example, you might do the following

  network of the SITE1_APP_JCAPS_Dev_VIP_NAT object

  Home 88.88.88.81

  network of the SITE1_APP_JCAPS_Prod_VIP_NAT object

  Home 88.88.88.82

  network of the SITE2_APP_JCAPS_Dev_Host_NAT object

  Home 88.88.88.83

  network of the SITE2_APP_JCAPS_Prod_VIP_NAT object

  Home 88.88.88.84

  network of the SITE1_APP_PACS_Primary_NAT object

  Home 88.88.88.85

  the APP_CLIENT_Hosts_NAT object-group network

  network-object, object SITE1_APP_JCAPS_Dev_VIP_NAT

  network-object, object SITE1_APP_JCAPS_Prod_VIP_NAT

  network-object, object SITE2_APP_JCAPS_Dev_Host_NAT

  network-object, object SITE2_APP_JCAPS_Prod_VIP_NAT

  network-object, object SITE1_APP_PACS_Primary_NAT

  Then you add the following configurations of "nat"

  NAT (inside, outside) 1 static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_1_NAT CLIENT_Host_1 non-proxy-arp-search of route static destination

  Static NAT APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT static destination CLIENT_Host_2_NAT CLIENT_Host_2 non-proxy-arp-search of source route 2 (inside, outside)

  NAT 3 (indoor, outdoor) static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination

  Note line numbers, we added the above commands. This allows them to enter the upper part of the ASAs NAT rules, and therefore, they will become active immediately. Without line numbers that they will only be used after when you remove the old lines.

  Then you can remove the "old"

  no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination

  This should leave you with 3 configurations "nat" who made the NAT source addresses and destination.

  Naturally while you perform this change you will also have to change the ACL Crypto to match the new source NAT. This is because as all NAT is done before any VPN on the ASA. So the destination addresses are Nations United for before VPN and source addresses are translated before VPN.

  If you do not want to make the changes without affecting the connections too so I suggest

  • Add rules to the ACL Crypto for new addresses (NAT) source. Of course, this must be done on both sides of the VPN L2L. You would still be leaving the original configurations to the Crypto ACL does not not the functioning of the L2L VPN.
  • Add new configurations of "nat" above without the line numbers I mentioned who mean you that they wont be used until you remove the "old".
  • When you are ready to be migrated to use the new IP addresses, simply remove the original "nat" configurations and the ASA will start the corresponding traffic for new "nat" configurations. Provided of course that there is no other "nat" configuration before the nine that could mess things up. This should be verified by the person making the changes.

  Of course if you can afford a small cut when then changing the order in which you do things should not matter that much. In my work, that connections are usually not that critical that you can't make these changes almost at any point as it is a matter of minutes what it takes to make changes.

  Hope this made sense and helped

• Hub topology and talk: can I traffic Internet road to PC at a radius of the site through the tunnel and NAT outside in the world on the 5520 hub?

  I don't know if it can be made to work or not, or if it's a mutually excluded NAT configuration that is not possible, but I have a 5520 ASA to my site central office with a fiber of 20Mbps Internet streams and two remote offices with ASA 5505 devices connected via DSL or cable modem and have finally got from Site to Site "spoke" VPN upward tunnels and run with the ability to route traffic to through a 'hairpin turn' speak-to-Spoke on the Hub Site 5520.

  I have desktop PC at each remote site speaks A & B that need to communicate directly with them to support a small group of work-style of the software point of sale that is actually hosted on a remote site A PC.

  PC on two remote sites must also be able to communicate with a credit card processing by the public Internet service, and I wish have the ASA 5505 units in each block of remote office as all traffic directly NAT'ed from each respective out on the local LAN PC straight Internet above each site cable modem or DSL modem. I want to force these PCs need to NAT their Internet-destination back through the ASA 5520 traffic located at the Home Office, on the VPN tunnels. In other words, I want the cable modem and DSL connections to route traffic strictly VPN encrypted to the Home Office and also behave like routers NAT for the local PC it.

  I can kill the 5505 prevents NAT for PCS in remote offices simply removing the rule dynamic NAT factory default for 'everything', but then I can't understand how to get my 5520 central to perform NAT which required of the remote PCs to talk to their service of Internet credit card processor without breaking the configs "NAT-free" necessary for VPN traffic to spoke-to-spoke to work. If I'm trying to put an entry static or dynamic NAT for a remote desktop on my 5520 ASA central, it breaks the VPN tunnel so that PC specific.

  Is that what I want to accomplish even possible with the ASA?

  Hi Neal,

  Yes, it's quite possible! below is a loss of things you need to do:

  (1) make sure of course on both the 5505 s of the ASA, you send ALL traffic from the local network through the VPN.

  (2) as Andrew mentioned, have the 'same-security-traffic permit intra-interface' command on the ASA 5520.

  (3) you do not have to have a configured proxy server, but it is also a good solution. But to make it work without her, assuming that the ASA 5505 remote subnets 192.168.1.0/24 and 192.168.2.0/24, add the config lines below to the ASA 5520:

  NAT (outside) 1 192.168.1.0 255.255.255.0

  NAT (outside) 1 192.168.2.0 255.255.255.0

  Global 1 interface (outside)

  Please note that 1 id, and the interface can be replaced according to the configuration you already have in place in the ASA 5520.

  I don't know what kind of NAT exemptions are at the origin of the questions for you, but if you can put a sanitized one of your ASA 5505 and ASA 5520 config, I can make suggestions concerning the exact configuration.

  Let me know if it helps!

  Thank you and best regards,

• Publish a server with NAT anchored through a tunnel VPN with ASA

  Hi all

  Thanks in advance for helping me out - I know somebody did, and I have trouble finding how do.  I don't know that I'm missing something simple.

  I have a client who wants to view a DVR device through a VPN tunnel that is published through the public firewall to collocation.  Endpoint DVR is endpoint ip assigned dynamically which tunnelle the host on demand (I know that the tunnel could fall).

  So I think / thought I could hairpin hair/policy nat this, but I'm not the best at this.

  Let's see if I can get this

  IP public 1.1.1.1\

  > External interface of ASA

  2.2.2.2 / private ip

  My config as I know it is pertinant is as follows:

  permit same-security-traffic intra-interface

  list of allowed incoming access extended ip any host 168.215.x.x

  Access-group interface incoming outside

  public static 168.215.x.x (outside, outside) 10.10.x.xnetmask 255.255.255.255

  I am running version 8.2.5 of the image of the SAA.

  If you could take a look and let me know what Miss me you please.

  Thank you

  Hello

  The problem here is of course the fact that we can not configure NAT0 without causing all traffic from the remote Internet can flow through the VPN connection.

  So I wonder if another type of NAT configuration would actually work.

  I would call it static political identity NAT if such a name exists yet.

  Something like that

  Note of DVR-POLICY-NAT-list of Direct HTTP access to VPN traffic

  allow to Access-list DVR-POLICY-NAT tcp host 10.10.2.253 eq 80 a

  public static 10.10.2.53 (inside, outside) access list DVR-POLICY-NAT

  This should basically do what

  • When the DVR is sending any traffic source TCP TCP/80 (essentially the traffic back to the connection from the main site) to ANY destination address (The Internet) then the host must translate to himself.
  • If we consider that NAT is performed before the VPN rules are processed this should mean that since we have concerns address itself, it must match the VPN rule only in this particular case where the traffic is TCP/80, which could only be the result of her replying to a link any destination TCP/80)
  • Which leads me to believe it shouldn't cause any problems with the Central connection on remote site (NAT0 is processed before political static NAT) or the RECORDER to Internet
  • Unless the DVR must be accessible directly via the Internet connection of the remote site. (He would send his answers to these HTTP connections outside with the originating source IP address) Or maybe even completely before connecting the phase failure. I have not tested.

  Hope this helps

  Be sure to mark it as answered in the affirmative. And/or useful response rate.

• NAT subnet in the network object group

  Can someone help me please? I'm rusty with VPN and Natting.

  Scenario: I need to share my internal-tunnel network. Traffic to 192.168.88.0/24 192.168.0.0/24 NAT when establishing a VPN connection for the objects that I defined in one group of objects specific network (Group1Servers). Internet traffic does not get this NAT 88, even by default.

  ASA5506-X, 7.5 ASDM, ASA 9.5

  Hello

  You can configure a static strategy of nat to translate 192.168.0.0/24 to 192.168.88.0/24 when the destination is Group1Servers, the CLI command:

  Create objects for 192.168.0.0/24 and 192.168.88.0/24

  network object obj - 192.168.0.0
  192.168.0.0 subnet 255.255.255.0

  network object obj - 192.168.88.0
  192.168.88.0 subnet 255.255.255.0

  Statement by NAT:

  NAT obj destination - source (indoor, outdoor) 192.168.88.0 obj - 192.168.0.0 static static Group1Servers Group1Servers

  You can view this documentation to setup NAT:

  https://supportforums.Cisco.com/document/33921/ASA-pre-83-83-NAT-CONFIGU...

  Given that this traffic goes through a tunnel of site to site do not forget interesting traffic must be configured with the translated '192.168.88.0/24' not the real network, which is a common error just keep in mind

  Best regards, please rate.

• Config of ASA 8.3 NAT pre then no. - NAT

  Hello

  I'm trying to set up a VPN S2S on a SAA V8.0.

  I want NAT 10.1.1.1 20.2.2.2 (as a result of conflict of IP address to the other side) then exempt from NAT cela on the remote VPN to the subnet of 30.3.3.3

  10.1.1.1 is based on the 'inside' interface, the cryptomap VPN is configured and applied to 'outside' interface.

  The ACL Crypto is:

  VPN line 1 permit access list extended ip 10.1.1.1 host 30.3.3.3

  (1) am not familiar with pre 8.3 config, only used 8.4 + in the past, can someone please send the config that NAT / No. - NAT will be.

  (2) in the ACL crypto you define real address (10.1.1.1) as the source or the Natt treat (20.2.2.2)?

  3) there is also an ACL on the external interface, you allow 30.3.3.3 (remote vpn) access to destination IP, the actual address (10.1.1.1) or the NATT (20.2.2.2) treat?

  Thank you!!

  It is not a double NAT.

  So 10.1.1.1 is simply translated to 20.2.2.2 when the destination IP address is 30.3.3.3.

  If this example is correct IE. your acl made reference to the real IP of 10.1.1.1 and 3.3.3.3 destination IP address.

  Then the static policy statement NAT uses 20.2.2.2 and refers to the acl.

  It is the NAT policy.

• Problem of static-dynamic ASA5505 L2L

  The two ASA5505 using version 9.2.3 tried ikev1 and ikev2, it worked before, but I don't know what the problem is now...

  I can read dynamic end tunnel ASA (default behavior), I mean that I have to ping asa (DynASA (config) # ping inside the 172.22.82.5).

• VPN site to Site with NAT (PIX 7.2)

  Hi all

  I hope for more help with config PIX.  TBH I would classify myself as a newb on PIX, only dabbling in it every 6 months or so...

  I have to configure a VPN site-to site between our UK and US Office, to replace our frame relay link.  I have configured multiple VPN site to site on the before PIX, so am reasonably okay with the appearance of the config of who.  What is a new concept for me is the needs of NAT'ing between the IPSEC tunnel.

  The U.S. Agency requires us to NAT source addresses (i.e. 192.168.1.0) usable on their side address (i.e. 143.102.89.0).  The tunnel must then be set to encrypt traffic between 143.102.89.0/24 and 172.24.0.0/14.

  I added the following config and hoping to test it at the U.S. office happens online today.

  If I Ping from 192.168.1.0 to 172.24.x.x source and run a SH NAT inside, the NAT translation seems good.

  is the intellectual property inside 192.168.1.0 255.255.255.0 outside 172.24.0.0 255.252.0.0
  static translation at 143.102.89.0
  translate_hits = 4, untranslate_hits = 0

  Could someone please go through the following lines of config and comment if there is no error?

  Thank you very much

  Kevin

  You can configure NAT/Global pair for the rest of the users.

  For example:

  You can use the initially configured ACL:

  policy-nat-dallas-list of allowed extensive access ip 192.168.1.0 255.255.255.0 172.24.0.0 255.252.0.0
  NAT (inside) 1 access list policy-nat-dallas

  Global 1 143.102.89.x (outside)

  The static statement that you configured previously will take precedence over the above. So the printer gets statically using a NAT to 143.102.89.10, and the rest can do another ip address 143.102.89.x PATed.

  Please note that for PAT, traffic can only be initiated from 192.168.1.0/24 LAN to 172.24.0.0/14, not the other way around.

  Hope that helps.
