I bought a Linksys HPRO200 Phoneline network router. When I tried to run online games (eg. Starcraft on Battle Net) its firewall blocks me out.
I located the ports that the games use and forwarded them to the computer which I play the games on. Doesn't work. I even went as far as turning off the firewall entirely by activating the Demilitarized Zone (DMZ), but that doesn't work either. The games ran smoothly for about 3 minutes, then the router's firewall suddenly shut down the internet connection.
Could anyone help me fix this problem? Thanks.
