Relayd + OpenVPN + Policy Based Routing

I have been successfully running Policy Based Routing together with OpenVPN to establish a VPN tunnel between a particular client on my LAN (by local IP address) to my external OpenVPN server. However, I just recently setup a secondary device with Relayd to serve as a wireless repeater/extender in my LAN. When the aforementioned client connects to the main router (running Policy Based Routing) through the repeater/extender running relayd, the routing does not seem to go through the VPN tunnel.

I would appreciate any help as to how I may determine how to fix this issue. Thank you in advance.
