No Traffic is routed through IPSec Tunnel

[JasonM]

Hello all

i am struggling with our setup:
Opnsense Firewall with multiple LAN and 2 WAN interfaces and a IPSec Tunnel to a remote MikroTik Firewall...

The Remote network (192.168.252.0) should be reachable from one of the LAN Networks (192.168.247.0)

it was working fine until i updated to OPNsense 23.1.11-amd64 and added a second WAN interface and created a WAN group for fallback (one is Tier1 and the other wan is Tier2)

so the tunnel seems to work and is having some traffic (see screenshot) but for some reason i cannot ping the remote network anymore, neither from the firewall (interfaces-diagnostics-ping) nor from a device in the lan network.

i already struggled arround a lot in the firewall roules with no success, but i attached the configurations here.

any help is highly appreciated, we have people unable to work without the VPN...

Little update. i deleted the gateway group and the routing started to work again...

now the question.... why?

is it not possible to use MultiWAN and IPSec VPN?
