On the new 2016 server forced a group policy update and saw the test port allowance added in the firewall GUI. I still cannot telnet to the port and netstat -ano still does not list it as listening. I then logged into a Windows 7 computer on the LAN and added a port allowance to test telnet from the servers. And here is the Service Management for Port Forwarding. In this window, you can't forward port 3000 to 81 only 3000 to 3000: I event tried to delete PAT rule and forward ALL inbound traffic (ports 165535) to 192.168.63.2. In this case, we would use external port 81, but still shows as 'closed'. Yep that would do it, from what I see it has a 'DVR' port forward with a huge range from port 4000 to port 40001. The minecraft server usually runs on 25565, that's in the range. This means that when you're trying to connect to the minecraft server the router is saying, wait a minute that's in the DVR range send it to 192.168.2.250 on either.

With some games and applications, it may be necessary to open one or more ports or setup port forwarding on your home router. Below are the steps required with most routers and additional help and suggestions with troubleshooting encountered issues.

Ports are often closed on a router to help prevent unauthorized access to your home network. Opening any additional ports on your router may decrease the overall security of your network.

If you want to open ports to give access to a game or an application like BitTorrent, make sure it is absolutely necessary. In some situations, it may be a firewall on your computer or router that is blocking access. Try temporarily disabling your firewall to make sure this is not causing your problems.

1. To use port forwarding, first determine the local IP address of the computer.
2. Open your router configuration.
3. Once in the router configuration, locate the port forwarding settings, often in a section such as Applications & Gaming or Port forwarding. If you are having trouble finding these settings, we suggest trying the Port forward site for exact steps on your router or refer to your router's documentation.
4. Once at the port forwarding screen, a screen similar to one of the example picture below appears.

Single port forwarding

Referring to the following picture as an example, with single port forwarding, you have different fields that need to be completed.

First, the Application Name is the name given to describe what the ports are that you are opening. In our example below, you can see this router has drop-down menus and empty boxes. If you are opening a common port such as FTP, selecting that option enables that port. However, in most situations, you need to type the name of the application. For example, you would type in the name of the game.

Check Port Opened

Next is the Externet Port and Internet Port. Enter the port you want to open in both of these fields. For example, if you were opening port 88, you would enter 88 in both boxes.

Next is the Protocol, which is often able to be either TCP, UDP, or both. If you are uncertain of the exact protocol needed, use both. If you do not have a Both option, create two open ports for both TCP and UDP.

Next is the To IP address, which is the IP address of the computer or networking device. This port is being forwarded to on the network.

Finally, once all these values are configured, check the Enabled box and click the Save Changes button.

Port range forwarding

If your application or game requires a range of ports, such as 6112-6119, your router should have a Port Range forwarding section (shown below). In this section, you would follow the same steps as those mentioned above, however, instead of entering an individual port, you would enter the starting and ending port number. For example, if you were given instructions to open port 6112-6119, you would enter 6112 as your starting port and 6119 as your ending port.

DMZ

Finally, if after enabling port forwarding you are still encountering issues with another computer or application seeing your computer, it may be necessary to enable DMZ. Often this setting is in the same area of the router configuration as discussed above and can be changed from disabled to enabled.

Why Is My Port Closed

Testing if an outside network can see the new port

Opened Port But Still Closed Captioning

Several services can test if your newly-opened port is recognized. We suggest trying Canyouseeme and the port checker tool from Portforward.
