We had a L2L VPN tunnel between our two offices. The remote office had problems with their Internet router so the ISP replaced a bad interface on it. Since the change, the tunnel has not been able to connect.
I looked at the log file and searching for the group of the remote office IP peer showed no entried. When I searched the IP just as a Client Address, I just get the following (repeatedly) and no other entries for it:
42292 03/22/2007 09:58:01.980 SEV=4 IKE/41 RPT=31831 <remote office peer IP>

I've never seen this before. I've cleared the ARP cache on all the routers here in our office but no change.
Any ideas?
