Chapter 3: Using EdgeOS
EdgeOS is a powerful, sophisticated operating system that
manages your EdgeRouter. It offers both a browser‑based
interface (EdgeOS Configuration Interface) for easy
configuration and a Command Line Interface (CLI) for
advanced configuration.
To access the EdgeOS Configuration Interface:
1.
Connect an Ethernet cable from the Ethernet port
of your computer to the port labeled
0
on the
EdgeRouter.
2.
Configure the Ethernet adapter on your computer
with a static IP address on the 192.168.1.x subnet (e.g.,
192.168.1.100).
Note:
As an alternative, you can connect a serial
cable to the
Console
port of the EdgeRouter. See
“Command Line Interface” on page 38
for
more information.
3. Launch your web browser. Type
in
the address field. Press
enter
(PC) or
return
(Mac).
4. The login screen will appear. Enter
ubnt
in the
Username
and
Password
fields. Read the Ubiquiti
License Agreement, and check the box next to
I agree
to the terms of this License Agreement
to accept it. Click
Login
.
The EdgeOS Configuration Interface will appear, allowing
you to customize your settings as needed.
Note:
To enhance security, we recommend that you
change the default login using at least one of the
following options:
•
Set up a new user account on the
Users
>
Local
tab
(preferred option). For details, go to
“Add User”
on page 33
.
• Change the default password of the
ubnt
login on
the
Users
>
Local
tab. For details, go to
“Configure
the User” on page 34
.

Basic Settings
Host Name
System host name
Enter a name for the EdgeRouter. The
host name identifies the EdgeRouter as a specific device.
For example, a .com URL typically uses this format:
<host_name>
.domain_name.com
Time Zone
Use Coordinated Universal Time (UTC)
UTC is the
international time standard used by Network Time
Protocol (NTP) servers. If your routers are located in
multiple time zones, then you may want to use UTC.
Time zone
To set your network to a specific time zone,
select
Time zone
and configure the following:
•
Select continent/ocean
Select your location.
•
Select country/region
Select your location.
•
Select time zone
Select your time zone.
Gateway
System gateway address
Enter the IP address of your
gateway. This will set up your default route. If you want to
set up additional default routes, configure them as static
routes on the
Routing
tab. See
“Routing Tab” on page
13
for more information.
Name Server
Domain Name System (DNS) translates domain names to
IP addresses; each DNS server on the Internet holds these
mappings in its respective DNS database.
System name server
Enter the IP address of your DNS
server (example:
192.0.2.1
for IPv4 or
2001:db8::1
for IPv6).
Click
Add New
to add additional servers.
Domain Name
System domain name
Enter the domain name of your
EdgeRouter. The domain name identifies the EdgeRouter’s
network on the Internet. For example, a .com URL typically
uses this format:
host_name.
<domain_name>
.com
NTP
NTP is a protocol for synchronizing the clocks of computer
systems over packet‑switched, variable‑latency data
networks. You can use it to set the system time on the
EdgeRouter. If the
System Log
option is enabled, then
the system time is reported next to every log entry that
registers a system event.
Automatically update system time using NTP
By
default, the EdgeRouter obtains the system time from a
time server on the Internet.
Click
Save
to apply your changes.
Management Settings
SSH Server
Enable
Enabled by default. This option allows SSH
(Secure Shell) access to the EdgeRouter for remote
configuration by command line. SSH uses encryption and
authentication, so it is a secure form of communication.
See
“Command Line Interface” on page 38
for more
information.
Port
Specify the TCP/IP port of the SSH server. The default
is
22
.
