Hi I have setup a Lans-to-Lan VPN tunnel between acisco vpn 3030 and a cisco 1605 router. The connection works great while is up but I have noticed that every day or every other day the connection drops around noon and doesn't come back up until sometime during the night. I have looked at the logs on the concentrator to see if I can find something there and I can see where the 2 of them are negotiating the connection and everything looks fine except for the following which I am not sure what it means:
-Could not find centry for IPSec SA delete message
-Responder forcing change of IPSec rekeying duration from 28800 to to 3600
Let me know if I need to post configuraions.
