Can’t connect to devices with OpenVPN active
-
I need some help with troubleshooting. I have a ProtonVPN client (OpenVPN) configured on pfsense on 192.168.2.x. Internet works fine, VPN works fine. On my main VLAN (192.168.120.x), I can reach my HDHomerun device just fine (192.168.2.55). However, when in the VPN subnet (192.168.2.x), I’m not able to reach my HDHomerun, even though it’s in the same subnet. However, if I don’t have the VPN active I don’t have any trouble connecting. Can you help troubleshoot?

it seems that the VPN client on your pfSense device might be causing an issue with routing or firewall rules. When the VPN is active, devices in the VPN subnet (192.168.2.x) can't access your HDHomeRun device, even though it's within the same subnet.

If you're policy routing traffic via the VPN then traffic meant for other local subnets would be forced that way unless you have bypass rules to allow it to be locally routed.
But that doesn't apply to traffic in the same subnet, that doesn't go through pfSense at all. So I would confirm that they really are in the same subnet. Make sure the mask is set correctly on all devices.
