Help with Site to Site VPN - static nat.

Sep 21, 2007 1 Replies

Group, I have a site-to-site VPN tunnel setup. Cisco Pix515 6.34 on both ends.



Both our companies have an internal network scheme of 10.1.20.x



I added the line to my config: static (inside,outside) 10.1.20.151 172.16.2.5 netmask 255.255.255.255



0 0

Everything is grand. We have connectivity.


*NOW* that machine, 10.1.20.151 can't traceroute anything past the tunnel. I think it's trying to send all traffic across the tunnel. what am I doing wrong?

Do i need to do policy routing? if so, can I get an example?



Gang, reading over my post, which was in a hurry, I don't think I was clear on what is going on. I have a site to site vpn set up. I have a machine - 10.1.10.226 that is nat'd to 172.19.1.1. That machine can ping the remote network fine, can ping my network and etc. What it can not do is reach the internet. I think the tunnel is trying to encrypt everything going out from that machine. If I do a tracert, it times out right before the firewall. A traceroute to the remote network is fine. I might be barking up the wrong tree, but I think something with the NAT is messing it up... maybe in the form of routing?

If it helps, here is my relevant config:

nat (inside) 0 access-list 102
