GuinnRouterX

The GuinnRouterX is a Ubiquiti EdgeRouter X that drives the majority of the DCARALAN network.

This page is intended to serve as documentation for some of the configuration aspects of the router.

Dual WAN

There are two WAN ports, eth0 and eth1, that are configured for automatic failover. KC5GOI sources internet to eth0, and N5LS sources internet to eth1.

Port Forwarding

Due to the complicated nature of the Dual-WAN setup, port forwarding is not supported by the regular port forwarding utility. To forward a port, follow these steps.

NOTE: The firewall policies are applied after DNAT translation. The port entered in the WAN_IN firewall section should be the port of the local device if it differs from the public port.
