OpenVPN not working via VIP

[Walkraut]

I am new to OPNsense and I am facing an issue that I am not quite sure how to solve.

I have two OPNsense VMs running on ESXi, each on a different host. For us they really only serve as OpenVPN servers and nothing more. HA is configured and the synchronisation between them is working fine. They are also configured to use a virtual IP and at least via http I can address them via their VIP. My problem is the OpenVPN part. OpenVPN works perfectly fine so long as the port forwarding points to the OPNsense's interface-IP. If I instead try to forward the traffic to the VIP, it won't work at all. I can see by the VPN log that the request won't even reach the OPNsense. If someone has some experience with this and can point me in the right direction, it would be much appreciated.

Did you select the VIP in Server interface?

Could you specify that?

In your OpenVPN server .. what is set in dropdown field "Interface"?

Oh damn! That was the crux. Thanks a lot, man, totally missed that.
