Wireguard connects but no access

I have successfully setup wireguard on my pfSense firewall and can connect to it using the app on my phone. In a similar method I have setup a client connection on my MT3000 (firmware 4.5.16) which connects to the firewall (as shown in the wireguard status page on the firewall).

Wireguard shows as connected on the VPN overview page on the device. To-from traffic shows at each end. However I cannot see anything via the connection - internet or lan.

If I ssh into the device the routing table shows no entry for wg0, only eth2 and br-lan. I’m guessing this is the issue but I don’t know why it occurs.

The config is as follows…

Address =
PrivateKey = <omitted>
MTU = 1400

AllowedIPs =
Endpoint = <omitted>
PersistentKeepalive = 25
PublicKey = <omitted>
