I cannot port forward to one computer on my LAN. But I can to any other.
It runs win10 and IIS. The IP is static, both the web IP and the local IP.
As I say, forwarding to another computer on the lan also running IIS works fine. So looks like the router is fine.
And this computer used to work fine, too.
I have reinstalled win10 using that web based MS ‘upgrade’ method that leaves your apps and files intact.
It has not helped.
Telstra (the ISP) techies spent 4 hours here and they couldn’t crack it.
Opera claims the site ‘refused’ to connect, if that’s any sort of clue.
All web interaction on that computer works fine (i.e. now, doing this).
Web based port checkers report all ports closed – even port 80.
