To setup a Port Forwarding Rule on your ICG-100 you will need to assign your end-device (firewall, router, etc) a static DHCP reservation before setting up your port forwarding rule. This will send all inbound traffic to the port in your rule to your selected IP address.
You can this do by configuring the ICG to assign a static IP to the firewall/router via DHCP in the local page. Steps are as follows:
Login to the web portal
Go to Network Configuration from the left-hand navigation pane
Go to Ethernet tab on the top of the page
Click Enable DHCP Reservations (check mark should be showing)
Click on New
Enter the MAC address (make sure to include colons) of the device to which you would like to assign a specific IP address
Enter the IP address that you would like to assign to the device (within the correct pool address range)
Click Save Changes at the top of the page.
Now that you have set the Static IP Reservation we can now set a Port Forwarding Rule.
Login to the web portal
Go to Network Configuration from the left-hand navigation pane
Go to Port Forwarding tab on the top of the page
Type the inbound interface if desired. Possible values are wan, lan, eth, wifi, or cell. Only traffic on the selected interface will be forwarded to the desired destination. If the Router is connected to 4G you will need to type cell.
Enter the Inbound Port numbers (can be specified as single value, comma separated list, or range)
Select the desired Protocol (TCP/UDP/ICMP)
Enter the Target IP Address (This will be the IP address created above)
Enter the Target Port
When complete, press the Save Changes button.
Note: There are 4 ports used by the remote management portal and the Web UI. These are 22, 80, 443, and 2222. If you need to forward any of these ports please reach out to support to discuss how this will affect your system.
