I have point to point T1 with 2x2811 routes. I need to Encrypt the data passing between the two routers. I have tried using and several types VPN of tunnels with limit success. Pings and trace routes work but none of my application work.
If you are able to ping and tracerroute after VPN tunnel comes up then there mayn't be a configuration issue. The symptom you described about the application connectivity issue frequently happens as a result of MTU problems due to IPSEC overhead. Can you try configuring the command 'ip tcp adjust-mss 1440' under the ethernet interface facing the LAN and test your applications.
If you are still having issues then can you provide us a sanitized a copy of the configuration.
