Some big benefits: - you can use a seperate IP for every server (service) on the same machine WITHOUT LETTING THE OUTSIDE WORLD SEE THEY ARE ON ONE MACHINE - after some time, if you decide to give a certain server (service) a dedicated machine, it requeres little to no DNS config changes. Users will not need to change settings, you do not need to alter DNS... - letting webservers use a seperate IP for a site (even if Virtual MultiHoming works great (e.g. FireSite VDM), older browsers like a seperate IP for a site/domain )... > If it'll let me run two SMTP servers (EIMS & LetterRip) on the same machine > then I'll happily give up one of my 16 IP addresses to become a secondary > address. If the soft supports it, it can be done (they both listen to a certain portnumber (25?) for calls on "their " IP.) > And if I am correct I can use VicomSoftRouter to setup the secondary address > in an easy to use window. I don't care for editing files with SimpleText. I don't think you need an extra config on the router for multiple IP's on one machine... Traffic for your subnet just has to be routed to the correct place.... Just my thoughts... J.
