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. --- John Morey <jmorey () mmintl com> wrote:
1) Is possible, using Linux, to setup a firewall such that it has public IP addresses on both sides. I thought I read something about this some time back but I can not find it now. If I remember correctly the trick had to do with putting both network interfaces on the same network but giving the external interface a network mask of 255.255.255.252 and the internal interface a network mask of 255.255.255.0. 2) If the above is possible, is it advisable? What are the up and downs as apposed to doing it the "normal" way where the internal machines have private IP addresses? Thanks for any help or info, John Morey jmorey () mmintl com
