I'm trying to setup Virtual IPs on my OS X Server, has anyone done this before? Or does anyone know how to set VIPs up?

Right now I only have 5 static IPs.

What !! No one knows how to create virtual IPs on OS X?

I think you are looking for this:

I have seen several in-depth threads on this subject here and at the support threads at Apple in the past. Try doing a search at both places. I have had no need to do this yet, but learned a lot reading some of those threads.

I tried doing a search on Macnn and Apple for "VIP" and 'Virtual IP", nothing came up!!. I basically need to setup my workstations on DHCP, and my OS X Server to supply non-static IPs.

Given 5 static IP addresses.

Mac 1 = 192.192.192.2
Mac 2 = 192.192.192.3
Mac 3 = 192.192.192.4
Mac 4 = 192.192.192.5
Mac 5 = 192.192.192.6 & 10.0.0.1 (router to private ip network)

Mac #5 could then become a DHCP server and issue 'private ip' addresses to the rest of the machines.

Mac #5 = 10.0.0.1 (router)
Mac #6 = 10.0.0.2
Mac #7 = 10.0.0.3
Mac #8 = 10.0.0.4
Mac #9 = 10.0.0.5
etc

Using a setup like this would require all traffic from any 10.0.0.x device to route non-local (aka internet traffic and/or 192.192.192.*) via Mac #5 (the router). OS X can do that now and Jag will make it even easier (share internet connection tab) but since I just got a simple router for $49.00 it was just as easy to do it that way since it didn't require me to use a machine as a gateway as well as the other stuff it was already doing. Remember if you shutdown or reboot Mac #5 then #'s 6+ will become 'an island' till #5 is back online.

When I hear VIP I usually think of a box (usually a web server) that has two or more IP addresses (but not for routing reasons). I have a box in the office that has 2 IP's from the same subnet and runs two different web sites. eg visit ip 1.1.1.1 and get 'Web Site A home page' visit ip 1.1.1.2 and get 'Web Site B home page'

Hope this helps...
