Hello,

 : Bah, I left my iptables book at home this morning.  I think 
 : mangle comes first, then prerouting, route/input, post-route.

Maybe one of these would come in handy [0], [1], [2], [3] and [4].

 : Nat carries additional overhead, but if the box isn't doing 
 : anything else and you have a decent amount of memory and traffic 
 : isn't too heavy.  I wouldn't worry too much.

Agreed.

 : If you don't need nat, then why bother.  You can put all the ACL 
 : statements you want on the forward chain.

Yes, indeed!
