create a tunnel and redirect traffic

[turtlebalubi]

hey guys

I'm trying to setup dns tunnel on macmini (as server).
iodined server works great and communicates with client.
all i wanna do is bridge tun0 and en1 so all traffic that comes from the client to server will go through it and be forwarded to the internet and back to the client.

i've been reading about bridging all over and understood it is not possible.
tried using ipfw and natd but nothing seems to work.

please help.
cheers
