Do both of you have UPnP enabled in your router?
Do you have the Upnp framework exception enabled in your Windows Firewall
exception.

Are either of you using any third-party firewall?


Gary,

Yes, UPnP is enabled on both our routers and appears to be
working -- the problem appears to be something in the particular OS
installs. On my end, I have two machines, one x64 the other. The XP Pro SP2
32-bit on both my machines fails to get the proper WAN IP address. Now, boot
XP 64-bit on the x64 machine, and it works. Now, boot Win2K3 Server on the
other machine, and it works fine.

On my buddy's end, he has a desktop and a laptop, both running XP
Pro SP2 32-bit. His laptop works and sends the correct WAN IP, but his
desktop fails, just like my two 32-bit XP installs.

Norton (Internet Security and A/V) are common to both of my 32-bit
installs. I have completely disabled Norton and tried it but it still fails.
My buddy has no 3rd party firewall, and we completely disabled the Windows
firewall on his desktop and it still fails there as well.

In Googling, I found out that Messenger uses Direct Play's
built-in UPnP engine, not the SSDP UPnP control point engine. On both my XP
32-bit installs and his desktop, the SSDP engine appears to be working fine.
We can both foward ports using the "Internet Gateway" properties from
Network connections. I wrote a simple Vbscript to get the WAN IP address
using the SSDP engine, and that works on both machines.

So my guess is it something screwed up with DirectPlay, but I
don't have a clue how to troubleshoot it. I tried reinstalling DirectX, but
that didn't help.
