Can't understand why this is not working. I perform extended pings but will not ping at all when before it did. I did make some changes since a new T1 was installed.

The VPN tunnel used to work until I moved to a different ISP which I'm using a loopback as the tunnel endpoint. Is this even possible?
You need to make sure that set peer x.x.x.x and crypto isakmp key xxxx address x.x.x.x on the other router are actually pointing to the new ip address of your router...Yes you can terminate on the loopback interface the command to do this is:crypto map map-name local-address interface-id where you interface id will be your loopback interface...for more information on this command, please refer to the following link:http://www.cisco.com/en/US/products/sw/ ... 8189please rate this post if it helps!Regards,
If found out about this command a few hours ago. Thank you though.
After adding the line as recommended, it changed nothing.
