I currently have two Cisco ASA 5100 routers. They are at different physical sites and are configured with a site-to-site VPN which is active and working.

I can communicate with the subnets on either site from the other and both are connected to the internet, however I need to ensure that all the traffic at my remote site goes through this VPN to my site here. I know that the web traffic is doing so as a "tracert" confirms this, but I need to ensure that all other network traffic is being directed over this VPN to my network here.

Here is my config for the ASA router at my remote site:

Thanks in advance,


  • I've hidden a IP from your route-line, you probably didnt want that out in the open. – pauska May 26 '10 at 9:41
  • I've also changed your "encrypted" passwords to "#####". However, you are now in danger of someone having full and unfettered access to your network. Cisco IOS passwords are a trivial thing to crack. I WOULD CHANGE YOUR ASA/VPN PASSWORDS IMMEDIATELY...and do not post those lines from your config again. – GregD Sep 21 '10 at 13:22
  • Oh man. I see this post is from May. Ugh. I sure hope you've changed your passwords since then. – GregD Sep 21 '10 at 13:26

From what I can see you're routing (everything) to a IP across your VPN. Everything looks correct.

  • Thanks for looking at it and yes I believe you're right, however I still have one more issue and that is, although the web traffic is being sent over the VPN to the router here as required, it is not being filtered by our Check Point firewall like everything else on the subnet here! I've changed my client gateway to the router here and the web traffic isn't filtered either, does this mean that I need to put in a tunnel-rule in the routing on either/or routers?? Please help! – Scott Clements May 26 '10 at 11:36
  • Is the default route pointing at your CheckPoint firewall? Should it be? – dunxd Sep 22 '10 at 11:12
