Araknis Networks® 310 Series Router
User Interface Manual
Settings > Port Forwarding
The External Address field displays the WAN IP for the system.
Network ports direct traffic between software applications running on network devices. Port numbers are
always associated with a host IP address and a protocol type, usually TCP, UDP, or both (TCP/UDP).
Network HTTP traffic defaults to TCP port 80. When an address is entered in the web browser, the request
is automatically sent to port 80 unless a different port is appended to the address. For example, if you
access a device at IP address 192.168.1.20, the request actually processes as if you entered 192.168.1.20:80.
When software from LAN devices need access to and from the Internet, additional ports may be forwarded
to the device to allow communication through the router firewall. Common uses for port forwarding include:
• Remote access for surveillance cameras and recorders
• Computer games and server applications
• Remote storage devices
• Remote access for network device user interfaces (WAPs, managed switches, power monitoring
devices)
Note – Many popular programs and protocols are set to use specific port numbers by default. For
instance, HTTPS services typically use port 443, and SMTP mail services typically use port 25.
Pro Tip – Today, in the event of a wan fail-over the port forward rules do not automatically apply
to the backup wan. Please plan your port forwards accordingly.
Port Forwarding Section
You can port forward against multiple WAN ports by using the external address drop-down.
Here you can set your protocol, the external port and WAN, and the internal target address for each port
you want to forward.
Port Triggering Section
Use port triggering to enable ports only when needed by watching internal ports for activity.
