Port forwarding

Goal

To access a client device on the LAN port of a router using a specific port and the external IP address of the Digi 6350-SR/6355-SR.

Setup

This example assumes the LAN ports are operating under default settings, which provide DHCP connectivity to devices connected to the router's LAN ports. For details on Digi 6350-SR/6355-SR default settings, see the Digi 6350-SR/6355-SR User Guide. For details using aView to configure the Digi 6350-SR/6355-SR, see aView User Guide.

For this example, you need:

• IP address of the client device on the LAN port.
• External port you want to forward to the client device.
• Port you want to access the client device on

Sample

The following diagram shows a sample setup of a router with a cellular WAN connection and a client's laptop connected to LAN port 4. In this setup, we want to access TCP port 443 of the client laptop from the external IP address of the router's cellular WAN connection. We will be configuring the router with a port forwarding rule to forward external port 10443 to port 443 of the client device's LAN IP.

Sample Configuration

Open the configuration profile for the router and make the following changes.

1. Under Firewall -> Port Forwarding, click Add to create a new entry.
2. Set the following options under the new port forwarding rule.

Interface: Modem

Prototol: TCP

Port: 10443

To Address: 192.168.0.186

To Port: 443
