link openvpn network on server with another network

[garlor]

I've got an ubuntu computer with wlan and ethernet interfaces, wlan is 192.168.1.0/24 being where the openvpn server is at, at 192.168.1.129, and eth is 192.168.100.0/24 being 192.168.100.2 the computer eth ip address

I want to be able to connect to the openvpn server on the wlan ( 1.0 ) and access eth ( 100.0 ), connecting with the vpn works, I get ip, but I don't have access to either wlan or eth0 hosts
