I followed the instructions on the port forward website but I couldnt follow them properly cos it wouldnt work. The info i got initialy from ipconfig /all gave me gateway IP very different from the one in the routers setup page. but the port forward instructions say to use the routers gateway and ip address but when i did that id get a warning that the subnets were different and if i hit ok it wouldnt work. It only worked when i put 192.168.x.x as the ip and as the gateway. That let me access the internet again but still the ips were dynamic when testing with what is my ip. Conversely when i tried putting in the ip info i got from the router as instructed by the instructions it just wouldnt work at all to access the internet. I was trying for an hour with no joy so asking here to see if anyone can see waht i have been doing wrong.
