OpenVPN connects but can't ping clients.

I have setup an OpenVPN server on Opnsense. I have a single client on a freshtomato router that can connect.

On the server side I can ping the server tunnel IP but not the client tunnel IP or any addresses in the client network.

On the client side the router can ping all addresses on the server network, but computer on the router can't ping anything.

I have checked the routing tables and they both look fine.

Any one have any ideas? I can post up some screenshots of the configuration if that helps.

Are both, OPNsense and the other router the default gateway in their local networks?

The can have different reasons. So at first ensure, that you can access the clients tunnel IP from the server.
Maybe you need to allow access with a firewall rule on the client router.

To access devices behind the client you need to create a client specific override on the server and state the client sides LAN at remote networks, and as well in the server settings.
