I already have 4 basic ipsec vpn tunnels with the same service provider over 1.5m dsl connections with small 871's connecting to a full T1 on an 1841 router at corp using the SDM gui - site to site vpn. Problem is, we just purchased 3 more sites and Im trying to set up 3 more vpns. I have tried to build, troubleshoot, rebuild, called the ISP, etc and cannot get them to traverse traffic AT ALL. The VPN tunnel shows "connected" on all three.. but I cannot ping from on wan interface to the other - weather internal or external. The remote sites are able to get on the web, etc. I will post the corp router setup as well as a remote. I am dying here - if anyone can give any advice, I would be greatly in debt.
Thanks so much!
