• Dual active/passive failover of ISP with static Nat on Cisco 1941

  Hello world

  I'm working on a configuration of a client and I have everything in place right now except the NAT' static ing.  The config fails during an ISP to another and track als and routes by default static weighted, the PAT rocking with course to each interface maps.  It is, is it possible to switch on the large amount of static NAT entries to the ISP of backup?  So far, everything I've read said no because you can have only one entry per ip/port combo, other than another configuration static NAT double server with a different IP address.  I just want to be sure before making my recommendations, all thoughts are greatly appreciated.

  Thank you

  Brandon

  In fact, you can also long as you use standard NAT ("ip nat inside source static") or not NVI ('ip nat static source') for your attackers. You apply the roadmap by the end of the static NAT statement to indicate which interface it should apply to. So, if you have something like this:

   ip access-list extended ACL_NAT permit ip 192.168.0.0 255.255.255.0 any ! route-map RM_NAT_ISP1 match ip address ACL_NAT match interface GigabitEthernet0/1 ! route-map RM_NAT_ISP2 match ip address ACL_NAT match interface GigabitEthernet0/2 

  Using port 80/tcp for example, you can do this:

   ip nat inside source static tcp x.x.x.x 80 y.y.y.y 80 route-map RM_NAT_ISP1 ip nat inside source static tcp x.x.x.x 80 z.z.z.z 80 route-map RM_NAT_ISP2 

  Just replace x.x.x.x with the LAN address of the machine that you are shipping y.y.y.y with the WAN address you are shipping on isps1 and z.z.z.z with the address of the ISP WAN you are shipping on ISP2. The static NAT will be conditional on the roadmap, at this point.

  This works with TCP, UDP, and IP forwarding, but does not require that you use an IPv4 address to your WAN address. For some reason, it does not work if you use an interface... so if you're using dynamic addresses, it will be more complicated.

• Public static NAT vs. Access-List

  Hello

  I have a question what is the best practice static NAT and access list. Example:

  Server (192.168.1.1) Web inside to outside (10.10.10.10) with the port 80 and 443.

  IP nat inside source static tcp 192.168.1.1 80 10.10.10.10 80

  IP nat inside source static tcp 192.168.1.1 10.10.10.10 443 443

  Or

  IP nat inside source static 192.168.1.1 10.10.10.10

  Access-list 101 permit tcp any host 10.10.10.10 eq 80

  Access-list 101 permit tcp any host 10.10.10.10 eq 443

• Static NAT by ASA

  I configured a static NAT through my ASA, which for some

  reason does not work - I think that the problem is with the NAT or

  der rather than the rule itself, but I would be very grateful if someone

  could you help me diagnose the problem.

  command line, the rule is: -.

  static (UKSCMGMT, management) 10.20.20.20 192.168.1.2 255.255.255.255 subnet mask

  My theory is that anything with a destination address of 10.20.20.20 would be considered to be 192.168.1.2 on the UKSCMGMT interface.

  in looking at ASDM rule looks like this

  Type the address of the Source Destination interface trans

  Static empty management 192.168.1.2 10.20.20.20

  There are a few rules exemption related to 192.168.1.2 - but they are host-to-host and should not affect the static translation.

  Yes, quite correct. You can configure NAT exemption by network instead of by each host. If you have guests that can be grouped in a subnet, configure as network instructions instead.

• Static NAT enable VPN site-to-site.

  Hello

  We plan to build VPN site to site, but, we have a single public routerable internet IP address to assign VPN on Site A, but Site B is ok.

  in this case, I think that we must use static NAT on the router, the simple diagram is as below.

  internal a subnet - router VPN - router for Internet of the Site - to - VPN - B B Site internal subnet.

  the final goal is to make the communication between internal a subnet and subnet B on IPSEC tunnel.

  OK, as I said, Site A having a public IP address, then it must use the static NAT and need to apply on the Site router.

  Router

  interface x/x

  Head of ESCR to the internet

  NAT outside IP

  !

  interface x/x

  Head of DESC to internal (VPN)

  IP nat inside

  !

  IP nat inside source static (like IP address x.x.x.x) public (as private VPN interface IP x.x.x.x)

  so, wouldn't be work without any problem? I think it will work, but I would find other one just in case.

  Hey,.

  Is that what you try to achieve:

  subnet A - A = vpn router = router B - Sub-B network

  and you need communicate between Subnet A and subnet via ipsec vpn b?

• Static nat and NAT ACL 0

  All,

  I have nat 0 ACL indicating that an ip address should not be natted, while a static nat statement saying we need natted. I just want to know that we will have precedence.

  Thank you

  It is of the order of operations PIX nat / ASA.

  the NAT 0 acl_name (nameif) has priority.

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

  2. match the existing xlates

  3. match the static controls

  a. static NAT with no access list

  b. static PAT with no access list

  4. match orders nat

  a. nat [id] access-list (first match)

  b. nat [id] [address] [mask] (best match)

  i. If the ID is 0, create an xlate identity

  II. use global pool for dynamic NAT

  III. use global dynamic pool for PAT

• Static NAT with asa 5520

  Hi all

  I have the following situation

  The following rules of the static nat

  static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255

  static (inside, outside) 200.200.200.200 tcp 8080 10.0.0.200 80 netmask 255.255.255.255

  I would redirect all packets destined for port 8080 and 80 IP address 200.200.200.200,

  to the private IP address on port 80 10.0.0.200.

  I tried to do that the ASA said there is already a rule, there is a way it be done?

  Kind regards.

  I don't think you can use port forwarding using the same local destination IP on port 80 in this way, fw will give you duplicate static entries.

  You can however get around and give 10.0.0.200 NIC a secondary IP address i.e. 10.0.0.201 and make electricity as follows.

  static (inside, outside) tcp 200.200.200.200 www 8080 10.0.0.201 netmask 255.255.255.255

  static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255

• Static NAT with the road map for excluding the VPN

  We have problems of access to certain IPs NATted static via a VPN.  After some research, we have learned that you have to exclude traffic destined for the VPN to the static NAT using a road map. So we did this:

  10.1.1.x is the VPN IP pool.

  access-list 130 refuse ip 192.168.1.0 0.0.0.255 10.1.1.0 0.0.0.255
  access-list 130 allow ip 192.168.1.0 0.0.0.255 any

  sheep allowed 10 route map
  corresponds to the IP 130

  IP nat inside source static 192.168.1.5 1.1.1.1 sheep map route

  Above worked to fix the VPN but the IP 192.168.1.5 is no longer publicly available via 1.1.1.1.  What seems to happen, is that the static NAT is not really work and this IP address is NATted with the IP of PAT.

  Any ideas on how to get this to work?

  Thank you

• Static NAT & DMVPN Hub

  Hello

  I don't think that will be a problem DMVPN supports the rays behind NAT devices, but I anticipate change my network for reasons of security and redudancy autour and putting a pair of ASA firewalls on my Internet collocation.  Right now I have a DMVPN race 3845, NAT & ZBFW.  I'm going to remove the ZBFW and move the NAT to the ASA, leaving only the DMVPN hub and routing.  If I create a static NAT mapping on my ASA to point to the DMVPN hub that will work?

  I think it will be, but I just wanted to be 110% sure.

  Thank you!

  Hi Brantley,

  DMVPN with static NAT on the hub is supported in the installer. Just be awear it there are limits.

  1, all DMVPN router, hub and spokes must be running at least 12.3(9a) and 12.3 (11) T code.

  2, must use ipsec transport mode.

  3, so need dynamic tunnel talk to rays, hub should work at least 12.3 (13), 12.3 (14) T and 12.3 (11) T3 code.

  See the configuration guide

• Static NAT question

  Hi Experts,

  Please help me on this. I enclose my diagram network with this post.
  My firewall is cisco ASA 5510 running with version 8.4 of software. I set up static NAT for all three servers (in the diagram, server 1,2 and 3). The question is, the static NAT works only with the first server. No trades do go to other two server (2 and 3). All servers are in the DMZ.

  When I remove the static NAT for Server 2 and 3, all traffic going to the server with the IP WAN address of the firewall, which means that the dynamic NAT works. I am also attaching the configuration file.

  (NOTE: NAT works for the 72.16.34.1 Server)

  Kind regards

• public static nat/global vs

  Excluding an access list, what is the difference between:

  NAT (inside) 1 172.16.5.10 net 255.255.255.255

  192.168.5.10 (outside) 1 global net 255.255.255.255

  static (inside, outside) 1 192.168.5.10 172.16.5.10 net 255.255.255.255

  Thank you.

  in static reality must be combined with the access list for a two-way communication... You are right in a sense that

  public static nat/global access-list =

  Basically, the rule is that the traffic is allowed more high to low infterface of default security

  BUT

  from the lowest to the highest security of communication you need an access as well as the STATIC list

• Tunnel + static NAT problem

  Hello:

  I configured a Pix501 to establish a tunnel from site to site with a 1710 in the central site and it works fine, except for a small problem. The central site hosts a Domino server that must have an entry static nat to allow servers on the internet to deliver mail to it. So, the problem is that even though I created a road map to avoid NAT in site traffic to site, the static entry seems a priority on the road map and the mail server is always using a NAT. So the SOHO cannot access to him. What can I do to fix this?

  I need to use an entry like this:

  IP nat inside source static tcp 172.16.34.22 1352 200.212.0.66 1352

  Any help?

  Thank you

  You must do the following:

  (1) create a loopback interface with an ip subnet that you are not anywhere in your network. Leave; s 10.10.10.0/30 say:

  loop int 0

  IP 10.10.10.1 255.255.255.252

  (2) create a roadmap to match traffic from the 172.16.34.22 Server destination and from the other side of the tunnel

  access-list 101 permit ip 172.16.34.22 host 192.168.0.0 255.255.255.0

  permissible static route map 10

  corresponds to the IP 101

  set ip 10.10.10.2 jump following (some address to the loopback interface)

  (3) implementing the road map inside the interface of the router where you have the server

  inter e0/0

  Static IP policy route map

  That's all

  Hope that helps

• Cisco IOS - how config static nat to NAT on the VPN

  Hello world

  I need help.

  I configured a VPN site-to site between two routers IOS. One of the routers already had a static NAT (172.16.100.1 inside to the public IP address), but this static NAT prevents remote VPN hosts access to the 172.16.100.1 home as it tries to the response to public IP NAT router configured.

  Does anyone know how to use static NAT for the inside to the outside, but don't not NAT inside to outside VPN traffic?

  I know how to make using a roadmap for "overload" dynamic NAT, but I can't? t see how you can use a roadmap on the static NAT statement.

  You can provide any help would be appreciated.

• 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.
