The Cheapest Dual WAN Router for Failover You’ll Ever Find

Working from home doing my work requires internet and energy. Something that you can’t take for granted when living on the beach in Brasil. The energy drops a second or two at least 10 times a day. Luckily we have UPS for that, but I need a Dual WAN Router for Failover.

If you don’t know Richard Parnell let me do a quick introduction. He’s the man behind the scene of all the keynote demos presented at Citrix Summit and Synergy.

He’s also the one paid by Citrix just to have fun & build the most amazing labs with the latest technology. These kind of traveling labs is used by Citrix System Engineers around the world and tracked by Tile.

Needless to say, I went with the $100 Ubiquiti EdgeMax EdgeRouter Lite ERLite-3 as recommended.

The EdgeOS is based upon Vyatta and are extremely powerful. I did some research but couldn’t find anything related to my needs and the latest EdgeOS Firmware 1.9.

So I headed over to UpWork and contracted an Ubiquiti expert for $40/hour (Protip: search for highest price & best rating). I even found PowerShell MVP Adam Bertram that created the GUI for my Automation Framework on UpWork.

Architecture

I have my main 50 mb/s fiber internet connection and a TP-LINK TL-MR3420 3G/4G Wireless N Router for failover when main link fails.

Shout out to my Netscaler mentor Dave Brett for the awesome Visio drawing.

Configuration

First you’ll want to connect to the router and upgrade the firmware to the latest release. After that just connect through Putty and dump the configuration.

In my setup I have external traffic routed to the EdgeRouter and from there Port Forward to 192.168.2.13 which is my Netscaler Unified Gateway.

As you can see from the above configuration, this router is extremely flexible. I can even add custom Hosts names to the router. No more custom hosts file entries on my computer(s).

To check the status of your configuration run the following command:
