I have a Sprint Mobile Broadband card for my Internet connectivity. It's USB, so I have my desktop computer doing the dial-up connection and sharing the connection on an Ethernet port. This desktop PC is running Windows XP Pro, and the connection is shared using XP's Internet Connection Sharing. So, if I connect to my WRT55AG with my laptop, and a program supports UPnP, will this router map the port out the WAN to the desktop PC? If not, is there a way around this?
