<![CDATA[2.2.6 <-> 2.3.x IPSEC - "no IKE config found for", "sending NO_PROPOSAL_CHOSEN"]]>I have a 2.2.6 installation at a remote site and a 2.3.1 in our lab.

I've had a stable IPSEC running between the two. A few days ago I found that IPSEC was dropping, and I couldn't get it to reconnect in the normal way. I even tried rebooting the 2.3.1 in the lab (at that time it was 2.3 release, now running 2.3.1 as of a few minutes ago).

The only "fix" to bring back the VPN connection is to reboot the 2.2.6 instance router.

Logs are attached. As are screenshots of the IPSEC setup page.

Usually that would mean either there is a mismatch or it's not matching the connection properly (remote gateway and identifier are not matching)
