@ChristianSchaaf you need to create a route where the next hop is the remote OpenVPN ip SORRY this only work if you use Wireguard as Client on computer.

@RGTESTED Do you have port forwarded 1196 UDP into the ER605?

@EskoS ER703WP-4G-Outdoor is not in router list. you have to go for cloud standard or selfhosted controller

@RGTESTED Does the router in the office have a public IP or is the router behind another router? You also need to make sure that the OpenVPN IP Pool does not overlap with any other networks.

@EskoS You using Cloud Essentials, your router is not supported on that platform.

@firefox111 I do a test with Wireguard site to site and splitt tunnel and OpenVPN server, no change on OpenVPN server config, you have to add routes like this in your wireguard config. but I recomand...
