Greetings MR Vets. I've a rather... interesting case. My main problem is with ports. I'm trying to play Diablo 2 again, and it tells me port 6112 is closed. I tried to see if it was the case with Transmission -yup. Then I tried www.canyouseeme.org and any port I try... It's closed. Including 20, 21, 22, 80. I think it's a miracle I can actually access the Web. I should note, I'm away from my place at the moment and thus can not access this internet's router options. However, despite the port in Transmission's accessing's looking closed, I can download stuff just fine. In short: Latest Macbook, Snow Leopard I can't access port 6112 (And strongly suspect that my computer's to blame at this. My old PowerBook used to give the same error randomly when I tried to play Diablo, even though my PC in the same place connected to same Wireless had no problems whatsoever) I can't see any ports I don't use a Firewall / Firewall in System>Security is closed. I use iAntiVirus and Mocha (related applications) Thanks for your time!
