However, port forwarding or port mapping is a process that open holes in your firewall, which inevitablely make your entire network system insure and it's great likely expose its vulnerabilities. Port forwarding can be configured when a network device needs access to the Internet from behind a firewall. In order to secure port forwarding, the following security practices should be followed to reduce the risk of cyber-attack against your Internet network devices.

3 Practical Ways to Reduce Risk of Port Forwarding:

  2. Ensure that the all accounts are set with very strong passwords. This is extremely important when a device is exposed to Internet.
  3. Avoid the usage of common port numbers but use a custom port instead. For example, port 80 is generally used in HTTP. It's recommended to use a custom port for a specific service. The custom port should comply TCP/IP port definction (range is 1-65535).
