Hi everyone, I need help with BHD LAN play this time:

I have 2 PCs, one with Windows XP, the other with Windows 7, connected to an ADSL 1Mega cable modem, one via cable Ethernet, the other with cable USB. Both pcs have DFBHD with NOcd patch and same files and maps.
But when I create a LAN match in one pc, the match doesn't appear in the other pc when I clic the 'Search' button, and I can't play de ninguna forma..

What I have to do? I have to configure something?
Can someone give me some of help? because i'm not an experto in that tema of network connections..
