Configuring Port Forwarding on a Router

Port forwarding directs inbound internet traffic on a specific port to an internal device. Common uses include remote desktop access, security camera systems, and hosted game servers. Log into the router admin panel and navigate to Port Forwarding or NAT/Virtual Server settings. Create a rule with the external port number, the internal IP address of the target device, and the internal port (often the same as the external port). Assign the target device a static IP or a DHCP reservation so its IP doesn't change. Common ports: RDP (3389), HTTP (80), HTTPS (443), FTP (21). Important security note: exposing services directly to the internet is a significant security risk. Avoid port forwarding RDP (3389) directly — use a VPN instead. Only forward ports for services that absolutely require external access, and use a non-standard external port when possible to reduce automated scanning attacks. Regularly review forwarding rules and remove any that are no longer needed.
