IPSEC connection dropping
-
Some more information. I set the lifetimes of phase 1 to 10 days and the lifetimes of the phase 2 to 1 day. After 1 day the vpn tunnel went down and did not come back up until I 1) Disabled both ends of the tunnel 2) setkey -FP on both ends of the tunnel 3) restarted both racoons 4) Reenabled the tunnels. I've tried many different ways to get the tunnels back up when they get in this state, but this seems to be the only reliable way I can do it.

A little late, I know, but you may want to try a new 1.2.3-RC3 snapshot. The NAT-T feature caused a lot of IPsec regressions just like the one you are seeing, and has been removed. If you try a snapshot from the past couple days it should behave a lot better.
-
I'm running 1.2.2 which I thought didn't have NAT-T. Trying to avoid running 1.2.3 until its stable and not a RC since this is a production environment. I still have the problem, but I've bandaged it by setting the lifetimes to 10 days so that the tunnel only drops once every 10 days instead of multiple times a day like before.
-
Ah, nevermind then. It may still be worth a try.
1.2.3 is just about ready to go, there are just one or two issues holding it up. It may even be in the next week.
-
Its just confusing to me that the tunnels from Pfsense <–> OpenBSD are stable, but the tunnels from Pfsense <--> Pfsense aren't. I would have thought it would be the opposite.
-
Hard to say why that may be the case.
Do you know what version of ipsec-tools is running on the OpenBSD box?
-
I'm not sure. Its an older box that I didn't set up and I'm not very familiar with OpenBSD. Any suggestions how to check the version?
-
It usually prints it in the log, wherever racoon is set to log to. It may just be in the main system log.
-
Hmm…looking at a ps I don't think its even running racoon. Looks like its just running isakmpd.
-
Well then I really have no idea on that one. Unfortunately, ipsec-tools does have more than its fair share of bugs.
They are nearing the release of a new version, but it won't be out in time for 1.2.3. Hopefully it will work out for 2.0, though.
