Hi all. The Shorewall documentation states:
"If all you want to do is forward ports to servers behind your
firewall, you do NOT want to use one-to-one NAT. Port forwarding can
be accomplished with simple entries in the rules file. Also, in most
cases Proxy ARP provides a superior solution to one-to-one NAT
because the internal systems are accessed using the same IP address
internally and externally."
What it does not include is, when SHOULD you use one-to-one NAT? Are
there situations where one-to-one NAT is a better choise than basic
port forwarding or Proxy ARP?
