IPSec P2 entry self-deleted after ISP Outage
-
I have an S2S IPSec tunnel between two PFSense locations. (Site A and Site B). Both are on 2.7.0. Mobile OpenVPN clients connect to PFSense at Site A and there's a Phase 2 entry on both sites to handle that OpenVPN traffic being passed through the IPSec tunnel.
Today the ISP on Site B had an outage that lasted about 2 hours. It's a dedicated fibre connection so there's nothing to do on PFSense but wait for them to fix their end. When they did, at some point after that Site B's Phase 2 entry for Site A's OpenVPN mobile clients disappeared.
This of course broke mobile clients from getting to Site B's servers - and I was pulling my hair out trying to figure out why until I went and checked the IPSec configuration that hasn't been touched in over a year.
Huh?
No one touched PFSense on Site B - I'm the only one with access.
Is this a bug?
