[Openvpn-users] tunnel between LAN and external gateway-interface

[martin <ed...@pm...>]

hi,

i have setup a openvpn-tunnel between two LANs. it all works pretty fine. but
i'm wondering if there is a possibility (or a special trick) to include a tunnel 
from one LAN to the external ip-adress of the other vpn-gateway. i would 
like to secure the mail-traffic, because this gateway is also the mail-server
(yeah, i know, its not recommended). anyway, i worked with freeswan before
where you are able to build such tunnels between a LAN and an external
interface (and even between two external interfaces). it seems to me that 
openvpn cant do this by design. is it possible at all? 
 
tia
