• NAT on IPSEC tunnel on cisco router

  Hello.

  I have a central router works as a Hup with two talks about routers, but rays routers has the same encryption domain network (the same local Network Segment), I need to do a nat on one of VPN tunnels to avoid conflicts in the concentrator, router. Can anyone help me?.

  NAT is performed before the encryption and decryption, so you should be able to configure your NAT as you please.

• IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static

  Hello

  My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:

  "Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)

  NAT takes place before the encryption verification!

  In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?

  Thanks for any help

  Best regards

  Hello

  Try to change your static NAT with static NAT based policy.

  That is to say the static NAT should not be applicable for VPN traffic

  permissible static route map 1

  corresponds to the IP 104

  access-list 104 refuse host ip 10.1.110.10 10.1.0.0 255.255.0.0

  access-list 104 allow the host ip 10.1.110.10 all

  IP nat inside source static 10.1.110.10 81.222.33.90 map of static route

  From my experience when a tunnel is launched on one side, but it is not on the other hand, that the problem is with an inconsistency of the isakmp and ipsec policies, mainly as ipsec policies change sets and corresponding address with ASA platform when a tunnel is not a statically defined encryption card he sometimes use the dynamic tag to allocate this vpn connection. To check if this is the case go ahead and make a "crypto ipsec to show his" when the tunnel is active on both sides, see on the SAA if the corresponding tunnel is the static encryption card set or if it presents the dynamic encryption card.

  I advise you to go to the settings on both sides and ensure that they are both in the opposite direction.

• The IOS IPSec VPN configuration Cisco router

  Hi experts,

  I have not configured the VPN for a long time on the routers so I want your recommendation on best practices.

  I need to run OSPF over it, so it must be GRE over IPSec

  I googled and I see the old type of config that I used to do with the use of the crypto map. Then I see config with profile Ipsec that is applied to the interface of tunnel (tunnel protection). I also see on the manual on isakmp profile...

  Is there an example of configuration that you can provide? This is site to site VPN with PAT most basic on the interface for the remote desktop for surfing the Internet. My routers are fairly recent. One is 2821 with new 12.4 T code and another 2921 router.

  Thank you

  Hello!

  I didn't have a corresponding exactly to your needs, but I did a. I set it up by hand while there might be errors in config.

• Cisco router 892 IPSec initiator?

  Hi all!

  I have the IPSec tunnel between Cisco router 892 (c890-universalk9 - mz.154 - 3.M4.bin) and Cisco PIX 515E (ver. 8.0 (4) 28) with 5 subnets behind PIX.

  PIX configured to deal with two-way-type of connection, but router support not =)

  So, when I generate intresting hosts behind the router traffic IPSec does not work. When I generate traffic hosts behind PIX , everything works, but I need to be initiator on the side of the router :-(

  Is there a way to make my initiator 892 tunnel Cisco IPSec router to work with Cisco PIX / ASA?

  I'm afraid I should replace the router to another device = (())

  Thank you!

• How to troubleshoot an IPSec tunnel GRE?

  Hello

  My topology includes two firewalls connected through the Internet "" (router) and behind each firewall, there is a router.

  The routers I configured a GRE tunnel that is successful, then I configured an IPsec tunnel on the firewall.

  I does not change the mode to transport mode in the transform-set configuration.

  Everything works; If I connect a PC to the router, it can ping another PC on the other router. However if I change mode of transport mode that they cannot.

  I was wondering how can I ensure that the IPSec tunnel WILL really works? How can I fix it or package tracking?

  Thank you.

  I was wondering how can I ensure that the IPSec tunnel WILL really works? How can I fix it or package tracking?

  To verify that the VPN tunnel works well, check the output of
  ISAKMP crypto to show his
  Crypto ipsec to show his

  Here are the commands of debug
  Debug condition crypto x.x.x.x, where x.x.x.x IP = peer peer
  Debug crypto isakmp 200
  Debug crypto ipsec 200

  You will see ACTIVE int the first output and program non-zero and decaps on the output of the latter.

  For the GRE tunnel.
  check the condition of the tunnel via "int ip see the brief.

  In addition, you can configure keepalive via the command:

  Router # configure terminal
  Router (config) #interface tunnel0
  Router(Config-if) 5 4 #keepalive

  and then run "debug keepalive tunnel" to see packets hello tunnel going and coming from the router.

• How can I bypass ipsec tunnel when do ftp?

  Hello

  I would like to make an IPsec VPN tunnel between my breanch and Headquarters Office (VPN router). I do FTP specific ip on the Internet without IPsec tunnel. This should be happenning on my website. then when users try to ftp://125.7.123.46 it should work around the tunnel and connect directly?

  Can any one give me a heads up how do I do this on my router?

  Thanks in advance,

  Reza

  Reza,

  In order to achieve this the 192.168.10.0/24 network server, here's what you need:

  ##########################################

  access-list 150 deny ip 192.168.10.0 0.0.0.255 192.168.2.0 0.0.0.255

  access-list 150 permit ip 192.168.10.0 0.0.0.255 any

  overload of IP nat inside source list 150 interface Dialer0

  interface Ethernet0

  IP nat inside

  interface Dialer0

  NAT outside IP

  #########################################

  With the above configuration you have access to Internet in the 192.168.10.0/24 network without disturbing the IPsec traffic.

  You have this double threat?

  IPsec Tunnel is in place and I can access the server on the other side via the beach of NATTED, for example a server behind the checkpoint with the IP 10.90.55.11 is accessible behind the ASA as 4.4.4.11, the problem is that I have never worked on a Checkpoint Firewall and servers/Server 4.4.4.11 that I can't connect to my environment to that checkpoint is configured with a Tunnel interface that is also supposed to to make NAT because of the superimposition of networks, at one point, I added an access to an entire list and bidirectional routing has been reached, but I encountered a new problem, I could not overlook from my servers public became unaccessecable, since all traffic was encrypted and get dropped to VPN: ipsec-tunnel-flow... for now the Tunnel is up and I can access the server via NAT 4.4.4.11, but can't access my internal servers. What did I DO WRONG (also, I don't have access to the Checkpoint Firewall (PE)) how their installation would be or how it should be to allow bidirectional routing?

  No, u certainly shouldn't allow 0.0.0.0 for proxy ACL. Again, your config is very good. In addition, package account, this show that traffic is going throug the tunnel in two ways:

  #pkts program: 3207

  #pkts decaps: 3417

  Also, looking at the meter, I can guess that some of the traffic comes from the other site, but does not return back (maybe that's where you can not connect from behing Checkpoint). If you say that 0.0.0.0 solved the problem, are there no other NAT rules for subnet behind ASA, so the server IP, for which you are trying to connect behind the checkpoint, translates into something else (not the beach, included in proxy ACL), when to come back?

• IPSec tunnel is disabled

  We have 3 IPSec tunnel set up between the cisco 1760 router and PIX 515e. IPSec tunnel is down by intermittent & son come only after compensation isakmp crypto & clear crypto its next to the router.

  do we need to configure something else in router and end of pix so that tunnels are still in Active state (QM_IDLE).

  Looks like the PIX loses its connection and the router is unable to say that the PIX has dropped.

  Try the isakmp keepalive on both devices configuration but also check network links extended features.

  How to disable permanently the spell check in Notes?
