Matchmaker connecting

[HammaH]

Try as I might I just can't seem to connect in the matchmaker room. I have all of the right ports open on my Linksys, have tried connecting wired from my dsl modem to my 'puter, and have even tried DMZ on my router. Last thing I can think of is, do I need to open my Netbios ports to receive queries to connect? I know most ISP's close those ports automatically now, but does anyone know if this will help? Thanks in advance.
