Okay, for folks like me who have a 1.6 Xbox, I have read, so far, that we can't use the BIOS that supports XBox Live blocking. From my reading, only the 49xx BIOS' do this and they don't work well on 1.6 Xboxes.
So, for those of you that can, I imagine bloking the ports on your broadband router would do the trick. Then when you want to play, simply unblock the ports.
I know it's a bit more of a pain, but if it stops banning, that's got to be a good thing.
So, my only question is, what ports does XBL use?
Works with V1.6. Has LiveBlocking.
