I have the latest Virgin Media Hub and I've been trying to setup port forwarding without any success. No matter what port I try, online port scanners show them as closed, even 80. I have disabled my software's firewall and my hubs firewall along with setting a port forwarding rule but nothing.
I have even tried DMZing my machine but this still does not make it work. What am I missing?
I use the various online port checkers and they show my ports as closed even port 80. Shouldn't port 80 show as open as this is what web traffic uses?
Does not work like that, going to a site thats port 80 like http://www.rjlsoftware.com/ you use a random source port and destination port 80 the NAT in router mode may choose to use the same source port but same destination port 80 then the incoming reply is mapped back by the NAT to your device.
Having port 80 open for Port forwarding is where traffic from the internet from a source port goes to destination port 80 to the NAT and is mapped to a LAN IP and the reply mapped back out to the internet.
