At this moment, I do not have the database to do research. I know some routers do NOT work with VP! The best bet you can do is either get Dlink wireless router, because Dlink to be one of router that is most compatible with VP. Other choice is to get another IP address from your ISP, and get switch to split the two public IP address, however this would require purchase of switch and monthly fee for additional IP address from ur ISP.
This is to remind that NOT all routers will work with VP! Linksys is the one who notoriously not friendly with VP, They were focused on netmeeting and other videostream, and don't give damn about Sorenson/Dlink VP.
