MS Messenger through Cisco running NAT

[Netslave]

Does anyone know how to get MS Messenger to run through a cisco running NAT ? It seems the source IP address is embedded at the application layer so when the destination tries to reply it tries to send to a non existant address.
The MS web site says you need a UPnP router, which Cisco IOS doesnt seem to conform to yet. They mention this at their web site but dont seem to offer an alternative....

Any help appreciated

Not sure what you mean, I use MSN Messenger, ICQ, AOL IM all through IOS NAT using the overload command.. It works fine for me, I do have a few problems here and there when doing File X-fers though..


More info please.

I run MSN through a NAT connection on a Cisco 1720 and have never had a problem!
