Openvpn server - no Lan ping

[thinksens]

Hello Dead OPNSense community,

 i 'm facing a problem to setup a Openvpn Server .
I am using OPNSense 19.1, up to date.
There os only one LAN interface configure on my OPNSense, and it's working behind a NAT.
I can connect with openvpn client and ping my opnsense server.
But i can't accès my LAN network.
By setting verb 5 i can see in client the cmd :route add <localnetwork> MASK 255.255.255.0
But i still can't reach my local network.
I 'v use the Wizard to setup the openvpn server.

Thanks for your help.

Best Regards
