Hi All,
I am having a strange behavior with a vpn configured between a Cisco VPN 3005 and a zyxel. Every 2/3 days, the tunnel goes down with the error message: "Could not find centry for IPSec SA delete message"
If I just log off the tunnel, it will reconnect and connectivity is back. It seems to me that this is a sort of incompatibility between zyxel and Cisco.
Any ideas?
Thanks, Pedro
