The problem I am having is simple. Every single port on my computer is blocked, according to several websites/programs I have tried (which would be backed up by the fact that whenever I try to host something like a game no one can ever join it).
Anyway. Don't try and tell me about port forwarding because I know all about it, how to do it, have tried doing it and it did nothing at all. I even tried cutting the router out and connecting my computer directly to the modem, nothing changed.
As for firewalls, I only have the default Windows firewall, which I have tried setting exceptions for and disabling all together. Nothing changed.
My ISP claims they are only blocking a few ports, mostly below 2000. So they shouldn't be the problem (then again, they have become quiet useless for a while now, so I wouldn't be suprized if they were blocking ports. Does anyone here live in the UK and use Virgin Media who has the same problem?).
And my cable modem has no sort of inbuilt router/protection either, so that can't be causing the problem.
So, does anyone have any idea as to why all my ports would be blocked? It is not my router, not a firewall, not my modem and not my ISP (apparently), so what else could be causing the problem, and how would I go about fixing it?

Have you tried another computer directly connected to the modem? It might be some setting you aren't seeing on your machine.

I can't try with another PC, but any console I connect to either the modem or router has no problem with connecting to, joining or hosting online gaming sessions.
And when I go to change the modems settings all I can change is "search frequency parameters" and "ethernet type" (no idea what either of those are, so I wont be changing them anytime soon). Other than those two there isn't much I can do other than look at infomation about the modem. So I don't suspect that the modem is the problem. The problem most likely is some hidden setting on my computer, but I can't find it, nor have I found any websites out there that hint at such a setting or how to fix it :[ | |
Likely your windows firewall. I know on xp even if you disable it it is not disabled. You need to go to your firewall settings thing, then click to the "Advanced" tab. Then uncheckmark the internet device. Otherwise it just turns off the firewall on the local network, but not for internet traffic.

Tried that already, as I said, it has no effect at all. I've tried allowing exceptions for programs, ports and internet devices. None of which have had any effect at all.
Hahahaha. Oh lord. After using a different port scanner it came back with a much more detailed report. "One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion." It was like that on more or less every port I tested, which is pretty weird if you ask me, because I have no firewalls at all other than Windows firewall, and that is allowing exceptions to the ports I choose, the web browser I use and my network connection. And my router is currently set to DMZ mode which should mean that all of the ports are wide open for the internet to see. I must be doing something seriously wrong if my computer is (apparently) as solid as a brick wall despite the fact that I am doing my hardest to leave it wide open for anyone to access! | |
