Title: Wireguard + CARP
Post by: Perun on April 07, 2023, 02:57:16 pm

Hi

I've a problem with CARP and Wireguard. If my fallback opnsense runs (CARP Backup) then seems that Wireguard lost some UDP datagramms. If I turn it off, then it works ok.
It seems the lose of the datagramms depends on the keepalive interval.
Does someone know such a problem?

I disable Wireguard on the backup router and wait till the patches are added to a release...
