My company uses the AT&T Global Network connection to transmit Medicare data. This software, by design, creates a VPN that shuts down any other network connections. My goal is to find a way to use this software on our network without taking down the use of the network for other users. Are there any special settings on the Linkysys router I could make so that the PC that ran the AT&T software was on a different subnet or port? If not, would a an additional static IP from my ISP solve the issue?
