MSN Messenger and Linksys WRT54G router?

Does anyone know what to configure to make MSN Messenger connect properly on a Linksys WRT54G router? Save for turning off the firewall and enabling wireless encryption (which shouldn't affect a wired connection) I haven't messed with any settings. I can't so much as get a connection! I know my software firewall isn't the issue, as the same thing happens when I disable that. I am using the newest firmware on the router as well. Any ideas?

One problem I had with MSN Messenger was that upon installation of XP SP2, the UPnP and related ports were blocked and so I could only use text (no audio/video). Check your firewall to make sure that there are exceptions for the UPnP-related ports.

I have a WRT54G using WPA encryption and I have the router firewall enabled and MSN Messenger works fine. I have made no special arrangement on the WRT54G.

UPnP has been enabled since I installed the WRT54G.

Thanks for the replies, folks. I have no idea what happened right, but I woke up this morning and everything was working fine. (And I don't think it was on MSN's end because other friends of mine were connected to MSN. At any rate, all three of my machines connect, and all report that I'm connected via a UPnP port-restricted NAT. So that problem is fixed. Go figure. I'm not about to look a gift horse in the mouth. :)

Still got a couple other things to work out, but they're not really wireless problems per se (actually, I suppose neither was this, so I apologize for the off-topic post) so I'll see if there is a more appropriate group to inquire in.

Thanks again!
