I use an Aliant modem along with this
particularly expensive modem (the one in the picture) which my brother decided was a good idea to get
this particular stufffest firmware that likes to kill itself every once in a while, and I cannot get any of my ports to open up as much as I try. I tried the port forwarding site, no dice. I tried Badspot's guide, no dice. I got my static IP set up and that works, port forwarding simply does not work.
Firewall is OFF, all individual blockland ports were added in as exceptions, pretty much out of ideas here.
Router ports are set up in the Port Range Forwarding tab, start: 28000, end: 28030, Protocol: Both, IP Adress: My static IP/same IP I get from the ipconfig /all in the cmd window. Enable: checked
I test my ports 28000 through 28030 with that port testing program off the site and no matter how much I forget up my connection preferences I still end up with the red "your port is NOT OPEN" message. I'm back to square one and trying to decide what else I should forget with.
I used to be able to host without port forwarding a year ago when I had high speed cable internet with a cheap router so it's unlikely that it's the firewall settings. I switched services, got a stuffty modem with about 3 loving options and got a router and since then I have not been able to host no matter how hard I tried.
