I did an expirement, i played jj2 from my dads computer. But jj2 ISNT registered on my dad's computer, its in the shared folder. So i i opened the ports on the firewall, and i played online, but i timed out every 30 sec.....And i stil couldnt play on my computer. Just some info thats all, ill try figuring this out more tomorrow, as for the software, my dad says its "Proxy Server" but im not usre if he is correct or not. Hope that helped
