[X4U] IP address on local network

[John Drake]

Dave,

Here is the info on my set up:
RCA External Cable Modem
Linsys Broadband Router with 2 Phone Ports RT31P2 Firmware 1.30.01
D-Link Gigabit Switch DGS2208
D-Link DNS-321 w/2-750 GB disk as a Mirrored Raid
Apple Extreme
The Router feeds the Switch, the Extreme and VoIP.
The Switch feeds the iTunes server, 5 computers (2 computers have airport 'n' cards and use the wired connect as a backup)
The Extreme connects 2 Computers and 1 Apple TV

Right now I keep loosing connection to the iTunes server when the IP changes, which makes it hard for the family to share photos/tv shows/music. 

Appreciate any help you can provide,
John
