I am having a problem implementing a change of public IP address in the VPN configuration of two routers.
The current configuration according to me should not be affected by me replacing the public IP. We did change ISP (AT&T) from COX in site A.
When I change to the new IP on the Cisco routers in site A and B it does not work. The tunnel only works with the old IP address from the previous ISP.
The configuration has the new Public IP address.
Here is this output from "show crypto isakmp sa"
12.1xx.yy.121 74.xx.yy.114 MM_NO_STATE 0 ACTIVE
Instead of the needed "QM_IDLE 1023 ACTIVE" result.
I suspect it's either an access list issue or a routing issue.
I am attaching the significant part of the configuration for both routers your review.
Thank you for your time on this!
