Why You Might Need Port Forwarding

Port forwarding allows external devices or services to access devices on your private network. This can be necessary for activities like hosting game servers, running security cameras, or remote desktop access. If you're using applications or services that require incoming connections, port forwarding ensures that traffic is routed to the correct device on your network.

What You'll Need

Before you can set up port forwarding, you'll need a static public IP address. By default, Capti uses CGNAT, which shares your public IP address with other users. This setup won’t allow you to forward ports, so you'll need to opt for a static IP.

How to Set Up Port Forwarding (Once You Have a Static IP)

  1. Gather Information: Start by identifying the IP address and MAC address of the device you want to set up port forwarding for. Save these details for later reference.
  2. Log in to Your Router: Access your router or gateway's settings through a web browser.
  3. Find the Port Forwarding Section: This is usually found under 'LAN' or a similar category in your router’s settings.
  4. Create a New Rule: Add a new port forwarding rule and enter the required details:
    • Device IP address: Use the IP address gathered in step 1.
    • Port: Enter the port number(s) you need to forward.
    • Protocol: Choose between TCP or UDP based on the service you're running.
  5. Save Settings: Apply the changes and restart the application or service you're configuring.
  6. Test: Use a tool like canyouseeme.org to check if the port is open and properly configured.

Security Tip: Set Up Access Lists

When enabling port forwarding, it's a good idea to set up access control lists (ACLs) or firewall rules to limit which IP addresses can access the forwarded ports. This adds an extra layer of security to your network by restricting access to only trusted sources, protecting your devices from unauthorised connections.
