Hi guys,
Just like to confirm whether I'm on the right track in setting this thing up. Network is as follows:
--->[internet]---[adsl router]----[DFL]----[server]
I'm forwarding everything in the ADSL router to the internal lan ip of the DFL.
I'm assigning the DFL's wan_ip the static public ip of the adsl router
I'm setting up NAT (under ip rules) for the internal clients
Would this result in a working environment?

(have to get it setup before putting it in a live environment). Do I need a default route as well?
Also, I'm struggling to use the interface to change the internal ip in the address list. Do I have to use the command line for that?
