Google Fiber - Dynamic DNS Setup on an EdgeRouter

Google Fiber's Network Box supports several dynamic DNS providers but I wanted to use one they don't currently support called afraid.org. Now that I have a router that can supports almost any dynamic DNS provider I can configure it!

Here's how to set it up on a Ubiquiti EdgeRouter.

From WebUI:

Go to the Service Tab
Then go to the DNS Tab
Press the "Add DDNS Interface" button
Select interface eth1.2 (assuming eth1.2 is your WAN interface)
Select afraid for the service
Set your hostname, login and password
Set the server to freedns.afraid.org
Press the Apply button



From CLI:

configure
set service dns dynamic interface eth1.2 service afraid host-name mydomain.mooo.com
set service dns dynamic interface eth1.2 service afraid login dyndns
set service dns dynamic interface eth1.2 service afraid password 123456
set service dns dynamic interface eth1.2 service afraid server freedns.afraid.org
commit
save

Testing the new configuration

From CLI:

Run this command to force an update:

update dns dynamic interface eth1.2

Run this command to see the status information for dynamic DNS.

show dns dynamic status

interface    : eth1.2
ip address   : 1.2.3.4
host-name    : mydomain.mooo.com
last update  : Sat Oct 17 10:53:36 2015
update-status: good

Notes:
If you have any uppercase letters in your afriad.org username, convert them to lowercase when setting your username on the EdgeRouter. (The afraid.org site is converting your username to lowercase when you login and the API calls the dynamic DNS client tries to make will fail if your username doesn't match exactly.)
