How to Open Ports

Three Methods:

This wikiHow teaches you how to open ports in your router's firewall or your Windows computer's firewall. The majority of ports in a firewall are closed by default to prevent intrusion; opening a port is a good way to solve connectivity issues—both between a device and a router, and between a program and a device—but it also opens up your network or computer to attack.

Quick Summary

1. Sign in to your router’s admin site.
2. Go to theFirewallpage.
3. Locate thePort Forwardingsection.
4. Enter or select the port.
5. Enter your computer’s private IP address.
6. ClickSaveorApply.
7. Restart the router.
