How To Find Free Ports In Windows 7

When you utilize a firewall — and you should — you change the manner your computer communicates with other computers on the Internet. The firewall blocks all incoming communications unless yous open a port in the Windows firewall to allow a specific IP communicate with your computer. For instance, if yous want to play many online games.

Most first-time firewallers are overwhelmed past the thought of opening a port. Although open ports are a security threat, sometimes you truly need to open one. However, you may need to open a port to enable a specific application. For example, when you select the check box to allow Remote Desktop, you're opening port 3389. That'due south the security price yous pay for enabling programs to talk to each other.In general, if yous need to open a specific port, the documentation for the program (game, torrent downloader, file sharer) will tell you . . . assuming yous read the program'south manual.

Cull Start→Control Console. Click the Organisation and Security link and then click Windows Firewall.

Yous meet the main Windows Firewall control window.

On the left, click the Advanced Settings link.

Yous run into the Windows Firewall sanctum sanctorum.

On the left, click Inbound Rules. Then, on the correct, under Actions, click the New Rule link.

Windows Firewall shows yous the New Inbound Rule Sorcerer.

Select the pick marked Port and click Next.

The wizard asks you to specify which ports.

In the Specific Local Ports box, type the ports you want to open up, separated by commas, and and then click Side by side.

For instance, in this case, the TCP ports that need to be opened are 418, 419, 420, and 421. The magician takes action and opens those ports to receive data.

Cull Permit the Connectedness and click Next.

The New Inbound Rule Magician wants to know whether it should apply this dominion if you're connected to a domain network, a private network, or a public network. The safest choice is to make it but open on your home network.

Cheque the boxes for Individual or whatever other desired network blazon, and and then click Next.

The wizard asks that yous requite the rule a proper noun and, optionally, a clarification.

Type a name (usually the name of whatever program required the opening). Click Finish.

Your new dominion appears in the Inbound Rules listing. It takes effect immediately.
