I have two locations. The primary Cisco 2800 router currently hiolds 50-60 VPN's and it connects to Cisco 850/870 series routers for each of them. I have a new site with 3 tunnels terminating on 3 unique Cisco 850 routers. The 850's successfully build tunnels to a third location, however, none of them build to my primary location. I have attached a debug from one RemoteRouter and also its config (all 3 sites are identical, barring unique keys and address'). The caveates that may be pertinent are that the 3 routers/tunnels all are NAT's on the remote sites at one common firewall (each has it's own unique NAT address). The other unique issue is that the external address on my MainRouter and the external address of the customers firewall all reside on one ISP (QWEST). I am having difficulty seeing what is affecting my connection. I have attached the debug info from RemoteRouter, the config from RemoteRouter, and the pertinent info from MainRouter.
