Hi
i am trying to set up a tunnel connection between twO 2800 routers A<->B
1) destination ip is-204.x.x.x-ROUTER A
2) source ip is 166.x.x.22-ROUTER B
The router B has the modem connected to GE0/1 whose interface ip is 166.x.x.22
The ip-forward-protocol nd is configured as below
ip route 204.x.x.x 255.255.255.255 166.x.x.21
Also tunnel 1 configuration,isakmp policy are configured properly
when i run show crypto isakmp sa it shows MM_NO_STATE,i checked the preshared key on both ends and they are same.
whenever i remove the ip address of the interface Ge0/0 and ip route i can ping the 166.x.x.21 which is the modem gateway.
when i revert back the configuration to the above ,the ip 166.x.x.21 cannot be pinged,the dsl connection is live though.
Please suggest ways to fix this so that i can make this tunnel state to QM_IDLE
