Hi, I'm having issues establishing a site-to-site vpn between us and a 3rd party's efility firewall (we're using a Pix 515 running 6.3). Their LAN range is 192.168.2.x but their IT people tell me they're NATting traffic to 126.96.36.199. The tunnel appears to be up but they cannot ping anything at our site. I want them to access 128.31.x.x, 128.51.x.x and 128.60.x.x on our LAN.
Just to complicate matters, I believe this site was set up with some port forwarding rules in the past to allow them access to specific servers on our site.
I've checked the logs and can see traffic from them (on 188.8.131.52) going to 184.108.40.206 which I believe is the port forwarding, but can't see anything else (they have a continuous ping to 220.127.116.11 on our network).
Unfortunately I dont know enough to determine if the port forwarding rules are affecting the site VPN, any help would be greatly appreciated.
