    Can't open port 8080 through Windows Firewall


    I have some home automation software (HomeSeer) running on a W10 machine on my network that has a web interface running on port 8080. I want to access this from other machines on the network. I couldn't access it by default so I created an inbound rule on Windows Firewall for TCP port 8080. But it still won't connect from other machines on the network. I know the problem is on the host W10 machine because when I temporarily turn off the firewall on that machine I can access the web interface from the other machines. For the rule I tried private only, and private+public+domain, and same result. How can I troubleshoot this?

    You do not have to. 80 & 8080 are always Stealth but open and close per each request to go through them.

    You need to turn off the firewall on the machine and only use the firewall on your gateway. That is probably where you are running into problems. Both firewalls are fighting against each other.

    Go to portforward.com for how to setup your gateway for proper port handling through its firewall.

    Isn't port 80 http, or am I forgetting something?

    Yes. Any equipment that you have on your network and want to use that port, you have to specify it in the hardware network menu. Only problem is, that it can foul up requests that come from a person web browsing, so it is always suggested to not use 80 or 8080 for anything else on the network.

    Even if the OP wants to stay with that port, they have to use the IP and the Port number (ie 192.168.1.100:80). Otherwise the router/gateway will think that you are doing an unauthorized request.

    I use a VPN to connect to my network when out and about. The Cisco RV-320 allows for PPTP VPN if you do not want to use say a OpenVPN server.

    Portforward.com is the best website when it comes to this area.

    I had to change the port to 8080 because apparently W10 has something that uses 80--everything worked fine on 80 before I upgraded from W7. Anyone know what is using 80 on W10 and how to shut if off?

    &0 is notmal http requests. 8080 is normal https requests. You can find a list online of all of the ports and what they are used for with TCP and UDP.

    I always use some oddball port that something on my network or software does not use. This will show listening ports in Windows. How Can I Tell What is Listening on a TCP/IP Port in Windows?
