Lan access with OpenVPN TUN on TomatoUSB

Hi there,

I have a router with Tomato USB by Shibby with 2 LAN:

br0 (LAN): 192.168.2.1/24
br1 (LAN1): 192.168.10.1/24
I also set up an OpenVPN server (TUN) to allow my smatphone to access to the LAN.

I can reach the br0 (I can open the Router web page) but I cannot open a web page on LAN1.

How can I allow the VPN to access to LAN1. Need I to add some iptables?

Thanks for the help!
