In this final post on configuring the ERL we’ll cover some miscellaneous items that don’t warrant a full post on their own. See part 1 for a list of all posts in this series.
The ERL can automatically update your IP address with a number of dynamic DNS providers. I’m using the following configuration with DNS-O-Matic:
Static DHCP Mappings
Sometimes it’s useful to assign known IPv4 addresses to specific machines. This example demonstrates how to set this up.
Changing the Host Name
The default host name for the ERL is
ubnt, but this can be easily changed.
According to the information available on various forums and blogs, in order to get maximum performance when using the ERL in place of the Google Fiber network box traffic in and out of the WAN interface must be tagged for VLAN 2 and have the VLAN priority set to 3, and hardware offloading should be enabled. I’ve never tried using the ERL with any other configuration, but I can confirm that I’m seeing good speeds with this configuration.
To apply these settings, delete most other settings from the WAN interface
duplex auto and
speed auto) and do the following:
You’ll also need to apply your IPv6 prefix delegation settings to the virtual interface.
Staying Up to Date
It’s a good idea to keep your router firmware up to date to ensure that you have all the latest security fixes. I haven’t found any way to receive emails or similar when new firmware is made available, but firmware announcements are posted to the EdgeMax Updates Blog.
In my opinion Ubiquiti’s EdgeRouter Lite is a very nice step up from the typical home or small office router for those who want more control over their networks. These posts have described configuration of some of the most common features needed for a basic home or small office network.
