I have a LAN (Client/Server)MS Small Business Server as A DHCP server, assigning IPs 192.169.0.xxx . Its switch is rackmounted and connects 14 XP_Pro workstations. I have ordered a UPS to protect and hold up a new 16 port 10/100 unmanged switch linking my Elastix Server and 14 handsets I want to use the same LAN (cabling) for my Elastix Network (Server and handsets.) What is best practice here: 1. A seperate subnet? 2. OR Can I run 2 DHCP servers ( 1 x MS SMS & 1 x DHCP Router) on the same subnet ie 192.169.0.xxx, with different ranges? 3. Put the Elastix System and it's handsets on a seperate subnet. Say 10.0.0.xxx ? and link 14 ports from the existing switch to the new switch. WHAT'S BEST PRACTICE?...Bearing in mind I might want to link (network)a second Elastix Box in a seperate geographical location later down the track ?
