• PIX vpn public dmz

  Hello

  I d wishes to establish a vpn to a pix firewall 515 and pos version

  7.0 (5) with a public dmz and nat translation.

  inside: 10.5.10.0/24

  outdoors: 1.1.1.1/27 (Beach)

  DMZ: 2.2.2.2/27 (Beach)

  distance inside the network:192.168.20.0/24

  My area of encryption should be: 2.2.2.3/32--192.168.20.0/24

  announcement I have a nat rule, which is:

  NAT (inside the dmz) 2.2.2.3 10.5.10.28 netmask 255.255.255.255

  So basically I want to translate the connections coming from 2.2.2.3 to

  10.5.10.28

  the vpn is configured correctly and set up both sides, but the nat rule

  with the vpn doesn't work.

  Built of incoming TCP connections to outside:192.168.20.82/34237 4619

  (192.168.20.82/34237) at dmz:2.2.2.3/22 (2.2.2.3/22)

  but I can t see any traffic on the 10.5.10.28 Server, I see instead:

  Built of incoming TCP connections to outside:192.168.20.82/34237 4619

  ((192.168.20.82/34237) at dmz:10.5.10.28/22(10.5.10.28/22)

  any help would be great!

  Could you specify just the line

  NAT (inside the dmz) 2.2.2.3 10.5.10.28 netmask 255.255.255.255

  should we read

  2.2.2.3 static (inside the dmz) 10.5.10.28 netmask 255.255.255.255

  Also are you terminating the VPN on the external interface of your firewall is to say what is the IP address of the peer to your end.

  You might not try

  static (inside, outside) 2.2.2.2 10.5.10.28 netmask 255.255.255.255

  * Edit - I meant

  static (inside, outside) 2.2.2.3 10.5.10.28 netmask 255.255.255.255 *.

  You need not actually traffic to DMZ, you?

  If not do you have IP addresses available in the public system on your external interface?

• ASA 5510 - VPN for DMZ with static rule?

  I have a 5510 ASA with a number of virtual private networks to other sites, allowing the traffic to and from the Interior of the networks.

  I need to establish a VPN rule to another site, but they have very little access to resources on my local network.  Because I am not in control of the SAA on this end permanently, I need to control that access on my 5510.

  (the following is not my real IP, but I use them for this example)

  My network: 10.100.1.x

  My DMZ: 192.168.1.x

  Internal network of other sites: 172.16.1.x

  I wanted to try to create a VPN between the site and the specific address of DMZ on my side and then allow access to internal addresses using static rules.  I decided to use a static rule to enable http access to a specific server (for example):

  static (inside, dmz) 192.168.1.200 tcp 80 10.100.1.200 80

  I need allow traffic here:

  access-list permits DMZ_IN tcp host 172.16.1.10 host 192.168.1.200 eq 80

  Access-group interface dmz DMZ_IN

  And of course, rules of access list which allow traffic that I can apply to the VPN:

  toSite host 192.168.1.200 ip access list permit 172.16.1.10

  And I don't want that traffic THAT NAT had between my DMZ and the other site:

  nonatDMZ of the host 192.168.1.200 ip access list permit 172.16.1.10

  NAT (dmz) 0-list of access nonatDMZ

  NAT (dmz) 1 0.0.0.0 0.0.0.0

  And, of course, the corresponding rules on their ASA must be in place, allowing traffic to 192.168.1.200, not NAT it.

  Everything is in place, but 172.16.1.10 to 192.168.1.200 http traffic never reaches 10.100.1.200.  I know the following:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  2 packet trace shows me that traffic is allowed.

  3. the works of static rule: to access the 192.168.1.200:80 of another host on the same interface, DMZ, which brings me to 10.100.1.200:80

  4. in the process of running a sniffer package on 10.100.1.200 shows 172.16.1.10 traffic does not reach it.

  So I'm banging my head against the wall here.  I'm sure it's something simple I'm missing.  Anything else I need to check?  Should I go about this a different way?

  Thank you.

  What you are trying to reach is not supported. You cannot configure NATing between the inside and the demilitarized zone interfaces while your VPN connection is from the external interface. The static NAT (inside the dmz) that you have configured will only work if the connection is initiated from the inside towards the demilitarized zone and vice versa.

  I think that what you are trying to reach is only allowing access on TCP/80 to10.100.1.200 for the VPN tunnel.

  You must configure your option 1:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  You can configure vpn-filter to limit the traffic to the only TCP/80, and he attributed to group policy that you have assigned to this particular tunnel group then.

  Example:

  web access list - allow permit tcp host 172.16.1.10 host 10.100.1.200 eq 80

  internal group-policy-strategy web

  attribute group web-strategy strategy

  value of VPN-filter web - allows

  global-tunnel-group attributes

  Group Policy - by default-web-policy

  Here is an example configuration for your reference:

• Issue of 8.3 to 8.2 NAT VPN SSL

  In the study and test SSL VPN on a SAA, I have the network as shown in the attached diagram. The configuration is the result of an ASA with 8.3 but our ASA is 8.2 and at this time I am not familiar with the new NAT configuration and controls in 8.3 or later and wondering if anyone can translate the

  Hello

  This seems to be a NAT0 / NAT exempt in the new 8.3 + NAT format configuration

  And I guess it would make sense that we are talking about VPN connections.

  It should be something like this

  the INTERIOR-NAT0 192.168.3.0 ip access list allow 255.255.255.0 192.168.100.0 255.255.255.0

  NAT (inside) 0-list of access to the INTERIOR-NAT0

  Naturally the names/networks used in the configuration can be different depending on your existing actual configurations on the firewall.

• 8.4 ASA using NAT VPN issue.

  Hello

  I'm working on a customer site and they have a problem with one of their VPN (we have other works well), but it is a major issue and I think it's because we use manual NAT and NAT of the object on the same server for different things.

  Traffic between indoors and outdoors:

  It works with a specific manual NAT rule of source from the server 10.10.10.10 object

  Inside

  SRC-> DST

  10.10.10.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 SNAT = VPN =-> 1.1.2.10 1.1.1.10 1.1.1.10-> 1.1.2.10 <3rd party="" fw="">

  It works with a specific using the NAT on the server of 10.10.10.10 object

  Remote

  SRC-> DST

  1.1.1.10-> 1.1.2.10 1.1.1.10-> 1.1.2.10 <3rd party="" fw="">= VPN =-> 1.1.2.10 1.1.1.10 1.1.1.10-> DNAT 10.10.10.10

  If we have the manual NAT and NAT object it does anyway.

  So the question is (as I am new to zip code 8.3 ASA) should not mix the 2 types of NAt and look at configuring it all with manual NAT or NAT object?

  With the NAT object out it does not work as it is taken in ouside NAT inside all:

  Dynamic NAT (inside, outside) source no matter what interface (this NAT to 1.1.1.1 then does not match the card encryption for VPN)

  and I tried a no - nat above that, but that does not work either.

  Straws and hugging come to mind try to configure a different config. Any pointers in the right direction would be great.

  Kind regards

  Hello

  I'm not sure that installing even with the explanation. Each NAT configuration I did for VPN used Section 1 Manual / NAT twice.

  You have configured the rule by default PAT that you use as Section 1 NAT rule. NAT rules in the new software are divided into 3 sections

  • Section 1: Manual / twice by NAT
  • Section 2: Purpose NAT
  • Section 3: Manual / double NAT (moved to section 3 using the setting "auto after")
  • The Sections are passed by from 1 to 2 and 3 in order to find a match.

  You should also notice that the Section 1 and Section 3 NAT has "line number" similar to the ACL parameter type. So if you have a default existing PAT rule configured for Section 1 and just add another Section 1 NAT rule without line/order number (VPN NAT) then it will just fall under the existing rule, making the new useless rule.

  I would advice against the use of the rule by default PAT as Section 1 NAT rule. Finally, this means that you be constantly watch and edit its configuration when you try to configure more specific rules.

  As a general rule 3 of the Section the PAT above default configuration would be the following

  NAT (inside, outside) after the automatic termination of dynamic source no matter what interface

  This would mean that you need to remove the old. That would mean as naturally as the change would temporarily dismantling all the current connections through "inside", "Outside" while you change the NAT rule format.

  If after this configure a NAT twice to the VPN (wihtout the setting "auto after"), it will be the rule in article 1 while the default PAT will be Section 3. Of course, Section 1 will be matched first.

  I'm not quite sure of what your setup of the foregoing have understood.

  You're just source NAT?

  I guess that the configuration you do is something like this?

• NAT/VPN Cisco ASA

  Hello

  I have a question on a Cisco ASA.

  We strive to set up a VPN connection with a provider of our using the 172.16.1.0/24 subnet now that they already have another customer using 172.16.1.0/24, then NAT traffic on a different subnet before connecting to the provider. Is this possible? If yes how can I configure something like this?

  172.16.1.0/24 is also used to access the internet.

  That's what I have right now:

  !

  internet_cryptomap_2 to access ip 192.168.0.0 scope list allow 255.255.252.0 (subnet provider)

  !

  card crypto internet_map1 3 match address internet_cryptomap_2

  internet_map1 crypto map peer set 3 (IP address of provider)

  internet_map1 crypto map 3 the value transform-set tubis-transformset

  internet_map1 crypto map 3 the value reverse-road

  !

  This VPN works, but only for the subnet listed in the cryptomap_2 unfortunately, I can't use 172.16.1.0/24 for this.

  Anyone has any ideas how to solve this problem?

  Kind regards

• nat VPN question.

  Try to find what happened.  I had the remote end raise the tunnel, as they can ping resources on my side.  I am unable to ping 10.90.238.148 through this tunnel.  I used to be able to until the interface of K_Inc has been added.  The network behind this interface is 10/8.

  I asked a question earlier in another post and advises him to play opposite road of Cryptography.  And who did it.  I was able to ping 10.90.238.148 of 192.168.141.10, with the config below.

  I am at a loss to why I can't all of a sudden.  A bit of history, given routes have not changed.  By adding the command set opposite road to cryptography, I find myself with a static entry for the 10.90.238.0 network is what fixed it initially so I don't think it's a problem of route.  The remote end had an overlap with the 192.168.141.0/24 that is why my side is natted on the 10.40.27.0.  None of the nats have changed so if adding the reverse route worked for a day, it should still work.  Any thoughts?

  What version are you running to ASA?

  My guess is that your two static NAT is configured above policy nat you have configured for the VPN?  If this is the case, move your above these static NAT NAT policy and you should see the traffic start to flow properly.

• Pool of dhcp NAT VPN to the LAN on router 2911

  I need nat the ips assigned by dhcp vpn to my LAN pool. My problem is that I do not know which interface to set my nat statement on since there is no interface that is in the same subnet as my dhcp pool. Any help would be appreciated.

  For remote client ipsec, you must have DVTI according to configuration described here:

  http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t14/feature/guide/gtIPSctm...

  'use ip nat inside' on the virtual model and 'ip nat outside' on the inside of the interface.

• Unable to VPN outside to the

  I just walked in this job to halfway through a passage of a software firewall to the cisco box. The config on this thing is crazy. I need help!

  I need a VPN client from outside to the inside, so the IT Department. can access the network hardware. Next, we'll add a few static VPN for other devices...

  In any case, I've tried everything even the wizard on a dev box to figure out what is preventing me from access to the network. I can establish a tunnel but can not get anywhere.

  I've included the entire config because she is poor and the problem can come from anywhere.

  Thanks for any help.

  Hello.

  It seems that you have not NOT nat the

  VPN traffic to the intended internal networks.

  I would add

  10.125.1.0 IP Access-list extended nat0 255.255.255.0 allow 10.0.0.0 255.0.0.0

  Of course you can adapt this more appropriate for internal networks, that you want to access.

  You should also link ip pool to your group policy.

  See how it goes...

• NAT VPN

  I'm havening problems with NAT over VPN. with current configs below it will complete the first phase of the tunnel and then stop because the ip address is not natted. If I put a permit in the statement of the permits it will be nat to internet host, but not via the vpn. If I put in a static nat statement it will nat and attempt to create a tunnel but I get the error (increment the count of errors on his, try 1 5: retransmit the phase 1)

  Ok. You must make sure that the ACl:s are the same (but in reverse) on both sides, which means that you probably need to remove a few lines on the Router 1. The ACL should look like this:

  BATSACL extended IP access list

  permit ip host 11.0.0.5 200.0.0.1

  permit ip host 11.0.0.5 200.0.0.2

  permit ip host 11.0.0.5 200.0.0.3

  Remove the keyword "log" of this line:

  IP extended access-list of the bats-nat

  permit log host 200.0.0.1 host 192.168.1.100 ip

  OK, now you've cleaned it, trying to make appear the tunnel again, try it with 200.0.0.1 and 200.0.0.2.

  Then, check the remote debugging.

• 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.

• Rule NAT VPN problem

  Hello people, I had a lot of trouble trying to solve this problem, but hoping someone here can enlighten me.

  I have a remote site that hosts a number of services that we manage remotely with an IPSec VPN connection. When connecting to the site connect us very well and can make most of the actions like RDP and connect to servers for maintenance, but a service fails to connect unless I have add a NAT rule exempt to the configuration of the router (ASA 5505).

  Once this rule in place service work, but other services that initially worked work stoppage. In short, this rule must be in place while doing a single task, but then contracted for other tasks. I hope that there is some sort of rule or behavior, I can add to the ASDM configuration makes it so I don't have to manually add this rule whenever I connect.

  Here are the details of the rule:

  access-list 1 permit line outside_nat0_outbound extended ip 192.168.15.192 255.255.255.192 192.168.15.0 255.255.255.0

  NAT (outside) 0 outside_nat0_outbound list access outside tcp udp 0 0 0

  When the connection is established without the rule in place the ASDM syslog shows these warnings:

  Deny tcp src inside: outside:10.100.32.203/135 dst61745 by access-group "inside_access_in" [0x0, 0x0]

  The strange thing is 10.100.32.203 is IP internal my host computer. This is not yet the external IP address of the network I connect from.

  Is it possible a problem with the VPN pool using a subset of the subnet of the VIRTUAL LAN inside? Inside VLAN is 192.168.15.0/24 and the VPN is 192.168.15.200 - 250. I am ready to reconfigure the VPN address pool but need to do remotely, and am unaware of how to do this reconfiguration safely without losing my remote access, since physical access to the router itself is currently very difficult.

  If more details are needed, I am happy to give them.

  Hi GrahamB,

  Yes, the problem with too much running in subnet.

  There are a lot of private-address available, so please create a new group policy and tunnel-group and fill

  pool separate to value ip address and remote with it, when the new cluster to solve your problem, can safely remove the old one.

  I hope this helps.

  Thank you

  Rizwan Muhammed.
