Hello,
we have a VPN from ASL 5.026 to a Cisco VPN 3030.
The VPN parameter are checked many times and are ok.
The problem is, that the vpn losts the connection and is down for a few minutes. Then everything is ok again.
Here are some values:
- IKE SA Lifetime (secs): 5400
- IPSec SA Lifetime (secs): 3600
Here are some log lines:
- Informational Exchange message for an established ISAKMP SA must be encrypted
- Informational Exchange is for an unknown (expired?) SA
- max number of retransmissions (2) reached STATE_QUICK_I1. No acceptable resp
onse to our first Quick Mode message: perhaps peer likes no proposal
But what can we do for a stable vpn?
Thank you for your help!
Regards
Thomas
