I followed all the directions provided.... enabled UPnP and opened ports on both my modem and router. I still always get strict NAT and have a hard time joining parties with friends. any other suggestions?

If you do a port forward you should have UPnP turned off. You can't port forward and have UPnP on at the same time. Also you need to give your console a static IP address.
