I have a T1 from my telephone provider. I also am installing Cable internet. I need to point my Administration vlan to the cable and my student vlan to the T1. But my Verticle voip phone system runs a phone management app that needs to stay on the Administration vlan and point to the T1. My goal is to allow my Administration vlan to access the phone management app but use only the Cable internet, because of the speed and reliability of the cable. Thinking of multi-nating. Can anyone help ???
