I downloaded cod 4 from internet (6 GB). I can play multiplayer with international servers both via ingame option and gameranger. But can not play in any servers from bangladesh. 3 of my friends play together in their room. the one who hosts uses link 3 and the other two use ispros and bdcom. they play very well. In speedtest.net it shows my isp is Mango Teleservices. Whenever i try to play in their room or any bd server room, it keeps me waiting (Awaiting connection...) and shows server time out. i have tried applying various cracks but doesnt work. I play on international servers very well with ping form 180-255.

any help to play in bd servers?
