[X4U] IP address on local network

Am I correct in assuming that you have the Linksys router providing  
DHCP services and the Airport only providing wireless?

If this is true . . . go into the Linksys with it's IP, username, and  
password . . .and then set the IP address reservations in there.  
You'll need the MAC addresses from each Mac (visible in Network in  
System Preferences); although some brands of routers will allow you to  
select a particular connection and turn it into a reservation without  
entering the MAC manually.

Alternately . . . you could just assign a static IP, subnet mask,  
gateway, and DNS entries to the iTunes server; and then just remove  
that IP address from the DHCP pool on the Linksys.

Given this arrangement . . .you could also simplify things by using  
the Airport instead of the Linksys entirely . . . unless the Linksys  
is required for your VOIP connection.

You could also consider connecting to the iTunes server via Bonjour  
networking . . . then it won't matter what IP the server has. You  
could also set the DHCP lease for forever (or as close to forever as  
you can choose) to keep the IP from getting changed.
