turning off firewall

i have SBC Yahoo DSL, and a 2Wire HomePortal Router that
came with a firewall. I want to know how to completely
turn off the firewall. i have an anti-cirus program, and
have no need for a firewall. not only does it conflict
with the zone. it also conflicts with Magic The
Gathering: Online. Also, if there isnt a way to turn off
the firewall. how do i add a pass-through? when it runs
through TCP/IP. i have the port ranges and port numeber
but the passthrough didnt work, plz help
