While firewalls can prevent intruders from accessing your computer network, they can also keep certain computer applications from connecting to your computer as well. If your firewall is blocking inbound connections from Skype, you may not be able to connect to other users, or you may find your calls are constantly dropping. If you are having problems using Skype, forwarding the program's ports may help you to maintain a better connection with other users.

Open Skype. Click "Tools" from the menu bar, then click "Options." Click "Connection."
Write down the number (usually four digits) shown in the box located near the top of the "Connection" window. This is the number you will input into your router's configuration page to open ports for Skype.
Click "Start" "All Programs," "Accessories," then click "Run." Type "cmd.exe" or "cmd" into the dialogue box. Press "OK" or hit the "Enter" key.
Type "ipconfig" into the command prompt, then hit "Enter." Write down the set of numbers next to "IP Address" and "Default Gateway." The "Default Gateway" is the URL for your router's configuration page.
Launch your computer's browser. Type into the address bar the set of numbers you wrote down for "Default Gateway." Hit "Enter."
Type in your admin name and password, then hit "Enter." Your router's configuration page should appear.
Search your router's options for "Port Forwarding," "Open Ports," "Applications" or some other related term. The location of your port forwarding page will vary based on your router's make and model.
Type "Skype" into the "Application" field. Type the port number you found on the "Connections" page into the "Port Range" field. If there is more than one port field, type the number twice. Select "TCP" as the protocol.
Enter your IP Address into the appropriate field. If necessary, check the "Enable" box.
Copy the information from the previous steps (the IP Address, the application name and the protocol) into two new fields. Change one of the "Port Range" fields to "80," and the other to "443."
Click "Save settings." Restart Skype.
Tips and warnings
- You may need to reset your router for the changes to take affect.
- To get the best connection to Skype, open all TCP ports from 1 to 65535. This, however, may compromise the security of your network.
