I have followed all of the instructions on Portforward.com, minus making a static IP(because my internet doesnt work when I do it, and because it's quite complex). Nonetheless, I've been able to host for about 2 years or so. Of course there have been problems before but they were easily fixed. Now I'm confused because I've forwarded my ports right (dynamic IP doesnt matter because I'm only one on the network anyway), never had any firewalls at all anyway, and because I stopped being able to host after I unplugged several cables in the back of my computer and put them back in. Any suggestions would be greatly appreciated.
