HighAvailabilty with OpenVPN - impossible to access Slave via VPN

[xsigndll]

Hi all,

I do have a master-slave configuration (HA) based on the CARP description here: https://docs.opnsense.org/manual/how-tos/carp.html

This works well. I can access all the internal networks and the machines connected to it (VLAN net, LAN net).

When I connect to the Master-VPN, I am able to log on to the Master-OPNsense as well. The only thing that does not work is accessing the Slave-OPNsense via the VPN (neither ping nor https) although they share the same subnet. I can access it totally fine by creating a tunnel though.

Without really going deep into any details or configs yet, my question is:

Is this a known problem/limitation? I assume it has something to do with the routing of the VPN IPs inside the OPNsense.

Best regards,
