Re: Firewall configuration questions.

[Rogue Bolo <roguebolo () yahoo com>]

There is no trick to getting a routed device, static
or dynamic, firewalled or not to use public addresses
regardless of the operating system. This is a
non-issue. Assign ip's as is appropriate. With regards
to using public or private ip's internally is really
more a question of whether or not you have a need to
route to internal hosts from the outside or not. It is
really a matter of choice, not normal or abnormal.
