i have installed TomatoVPN on 2 WRT54GL and successfully setup vpn-tunneling using TLS auth (other settings as default). openvpn server router 192.168.2.1 255.255.255.0 openvpn client router 192.168.1.1 255.255.255.0 with a host on the client side (eg. 192.168.1.100), i can ping hosts on the server side (eg. 192.168.2.1, 192.168.2.100). BUT i cannot do the opposite, eg. on 192.168.2.100 host ping 192.168.1.1 or 192.168.1.100. what do i need to do to enable this on my tomatovpn routers?
