Re: NAT traversal problem with Messenger RA.

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?

Have you tried upgrading to Windows Messenger 5.1?

Jason,

Unfortunately, v5.1 didn't solve the problem. A buddy and I were
playing around with this some more, and this is the situation:

We both have two machine LANs behind routers, his a Linksys and
mine a D-Link. All machines are running XP Pro SP2 with all updates fail
to send the correct WAN IP address in the RA ticket. One of his machines
fails as well, but his laptop, connected via wireless works.

Now, one of my machines is an AMD x64 and I have an install of XP
64-bit on it. I booted it up and it worked fine, sending the correct WAN
IP address still using v 4.7 of Messenger So XP 64-bit works on that
machine, but the 32 bit XP does not.

Then on a lark, I have an evaluation copy CD of Win2K3 server and I
installed that on my other machine (32 bit only) and it was able to do NAT
traversal with RA fine as well.

I suspect this is some configuration problem, some conflict or
mis-setting that is common to both my 32-bit XP installs but not the other
OSes, and is also common to one of my buddy's machine but not the other.
