Also if it still does it with manual port forwarding I'd be inclined to blame the router. I'm not certain what that means in MSN, what is the whole message? I don't use uPnP or any port forwarding with Pidgin and it doesn't complain, although it means you can't do p2p file transfers (they get routed through the MSN servers instead and it's painfully slow) but I rarely use that feature anyway. Besides, MSN IM manages fine with STUN and I don't like uPnP so avoid it where possible, but I digress. If it means your PC has symmetric NAT it could mean you've put your PC's IP in the DMZ, check that because it's not something you want.
