Port Forwarding Configuration – Support Document
Overview
Port Forwarding allows external users from the internet to access internal LAN devices or services behind the router.
This is commonly used for:
Remote camera (CCTV) access
Remote desktop / server access
Hosting applications or web servers
IoT device access
Third-party integrations
Port forwarding works by mapping an external WAN port to an internal LAN IP address and port.
How to Configure Port Forwarding
Navigate to Configuration → Port Forwarding
Enter a Group Name
Select:
Devices
Device Tags
Network
This defines where the port forwarding rule will be applied.
Create Port Forwarding Rule
Enter the following details:
Rule Name – Friendly name for identification
Protocol – Select TCP / UDP
External Port – Public port accessible from internet
IP Address – Internal LAN device IP
Internal Port – Port on LAN device where service is running
Click Create Port Forwarding
Multiple rules can be added using Add Port Forwarding Rules
Example Configuration
Rule Name | Protocol | External Port | Internal IP | Internal Port | Use Case |
CCTV | TCP | 8080 | 192.168.xx.xx | 80 | Remote camera access |
RDP | TCP | 3390 | 192.168.xx.xx | 3389 | Remote desktop |
WebServer | TCP | 8443 | 192.168.xx.xx | 443 | HTTPS hosting |
How Port Forwarding Works
External user connects to Router Public IP + External Port
Router checks port forwarding rule
Traffic is forwarded to Internal IP + Internal Port
Internal device responds back through router
Important Requirements
Router must have Public WAN IP
Internal device must have Static IP
Service must be running on internal device
Firewall must allow the port
ISP should not block required ports
Troubleshooting Port Forwarding
If port forwarding is not working:
Verify WAN IP is public (not private NAT IP)
Check device reachable from router LAN
Confirm correct internal port/service
Ensure no duplicate or conflicting rules
Verify ISP port blocking
Reboot device after configuration
Best Practices
Avoid using default ports (security risk)
Use strong authentication on internal services
Limit exposure to only required ports
Maintain documentation of all rules
Remove unused port forwarding rules
Conclusion
Port Forwarding enables secure remote access to internal services when configured correctly. Proper planning, validation, and security practices are essential to ensure stable and safe network operation.
