Report "How can i open ports for this? it seems to be blocking ports 20 and 21 which i need open for a game i was wanting to play. i opened the ports on our router(our internet is ran from the modem into this box into the router), but its still blocking the game if i try to play it through the router. but if i connect straight from the modem to my computer it works fine. so the only answer should be that this zonet box is blocking it, is there any way to open those ports?"
