OpenVPN and IPSEC strange and unstable

[lshantz]

I used OpenVPN for several years until the major changes made and have not got it going again. We finally made an effort to get it running and we thought all was well. We put a remote firewall into production after testing on the work bench and all was good. It stopped working after about 24 hours. We don't know why. We went out and turned off the static TLS and it still does not work. Out of frustration we went to IPSEC. Got it working. Less than an hour later, it too stopped working. We have spent hours trying to discover what is wrong. To the point, we have started looking at alternative firewalls.

It just struck me that since we are using CARP, is there a possibility that CARP is somehow causing us all this grief. I was quite surprised to see so little traffic on this topic. Either not very many people are using VPN here, or they are not having the trouble. But for it to work fine one minute and then stop with no changes being made is driving me mad.
