My netgear has it built in. Should be nice and simple, the only other thing to bear in mind is security. Opening up ports on your router is like knocking a hole in a wall and adding a door. Of course you can lock a door, but it's not nearly as secure as the wall it replaced. I get all sorts of knobs trying to r00t my boxes at home. I don't think the empeg has had many security rollups recently!

Maybe consider building a VPN instead? My netgear has that built in too.
