Yep.. Mod_rewrite can be used for this. Didn't think of that since I was
thinking "Proxy" only.

That being said, using mod_rewrite I can rewrite on-the-fly to the
Nat'ed address. But what if the add has a DNS entry? Say

www.example2.com and www.example1.com both has the same external IP (say
10.1.1.1)

but www.example2.com is actually a NAT'ed server inside the firewall and
behind apache? What then?
