Port forwarding not working!

[JustHans]

I'm trying to host a server for a game. I have done this several times before (on the same computer and same network), but now it just won't work. I can connect to the server through my IPv4, but not through my public IP.

I have had a similar issue before where it wouldn't work because I had my computer connected to a nest-WIFI point that was then connected to the primary point.

I have set up the port in the settings, I have set up an IP reservation and i have made sure that my computer is connected directly to my primary nest-point.

I'm not sure how WAN works, but it's set to DCHP and UPnP is disabled.

Please help

Hey @JustHans .

Check the settings on the modem. If the port forwarding worked previously and doesn't now due without anything changing in the port forwarding settings, then it is likely due to an ISP update. 

• Verify that the ISP does not refresh the public IP. This is common practice and can be overridden by changing the modem settings to set a static WAN IP
• Verify that the port forwarding settings needed for the setup have not changed themselves. Sometimes these will be updated/modified on the manufacturer/hosts side which can result in similar issues
• This article can also be of assistance to verify the port forwarding was setup correctly. If you have IPv6 enabled on the network, you will need to set up the port forwarding for IPv6 or disable it (Port forwarding or port opening )

Thanks for the reply @PatrickP_Viking 

1: The ISP did actually refresh my public ip, however I did catch that before testing the server

2: As far as I know there has not been a change in the server settings (if that was what you meant). The server port is still the same and the game version has not changed (I also tested different versions).

3: IPv6 is disabled. I have tried the support chat. They said to change a couple settings and restarting the network, however that did not work

The funny thing is that I have not changed anything (on purpose). The last time I used the server (a couple months ago on the same computer and on the same game version) it worked fine.

Turns out my ISP has swapped to only allowing port forwarding if you have purchased a permanent IP (Due to the IPv4 shortage)
