Merry Christmas!
I have tried to migrate my small network from Sophos XG over to OPNsense but without luck.
My setup is/was:
- Virtualized OPNsense with direct internet conneciton + static IP
- Virtualized OPNsense with NAT
- Turris router (CZ modified OpenWRT)
As I have two remote sites I wanted them to connect via ZeroTier S2S VPN + OSPF routing and here my pain started.
From Turris I was able to ping the NATed OPNsense without any issues - worked flawless.
From my local OPNsense I had an average ICMP package loss of around 50 %.
Also OSPF routing was not working due to that.
Any idea what might be the root cause?
