How to Fix an Open Proxy on a Computer


An open proxy on a computer is an area from which the computer is vulnerable to attach from hackers or phishers (individuals trying to obtain your personal or financial data). Open proxies most commonly occur due to negligence when configuring your network security. Fixing an open proxy means closing the ports associated with that proxy on your computer's firewall, allowing no network traffic to enter or leave from that area. This means configuring your router (the device that sends data between computer networks) to seal off these items, a process that takes anywhere from 20 to 60 minutes.

Things You'll Need

  • Router instruction manual
  • Open your Internet browser and type in the address listed in your router instruction manual that came with the router to access your router settings. This address is typically something like, but it can vary, so consult your operating guide. If you have lost your hard copy of the manual, you can normally download a version off of your manufacturer's support website.

  • Enter your user name and password for the router to access settings.

  • Navigate to the Security page for your router settings.

  • Block ports 50050, 3128, 80, 3124, and 8080, as these are the most commonly used ports to hack into an open proxy. The method for blocking a port varies depending on your particular network router, so here again consult your instruction manual for the precise method.

  • Exit out of your browser to save changes.
