HOWTO: Upgrade EdgeOS firmware
https://help.ubnt.com/hc/en-us/articles/205146110-EdgeMAX-Upgrading-EdgeOS-firmware

ER-X
Note: The ER-X/ER-X-SFP/EP-R6 has more limited storage, and in some cases upgrade may fail due to not enough space. If this happens, remove the old backup image first (using "delete system image" command below) before doing upgrade. The system will always have at least 2 images so you are alright to remove the older one.

Command Line

show version show system image delete system image show system image add system image https://dl.ubnt.com/firmwares/edgemax/v1.9.7/ER-e50.v1.9.7+hotfix.4.5024279.tar show system image show system image storage sudo reboot show version show system image logout

Firewall Regions Explanation
WAN_IN is from the internet, through the router, and onward to your LAN. In very general terms, you want to drop 90% of this mess - it's script kiddies, port scans, nigerian princes, and anyone else you don't want able to head through your router. Obviously, you're gonna want to allow ports 80, 443, 25, and others if you're running those types of services. If you haven't got any idea what I'm talking about with those three ports, better to not open them.

WAN_LOCAL is from the internet to your router, with no intention of going farther. Best to just drop everything on this interface -- unless, for example it's a router at a remote site, and you've got a static at your main site, so you allow traffic from 10.10.x.y/28 (note, I'm using private address space as an example, real world would depend on your ISP).

LAN_IN is everything inbound to the router from your LAN (e.g. 192.168.1.0/24) that's destined for somewhere else (WAN, other LAN such as 192.168.2.0/24). In a SMB, or SOHO setup, this is probably explicitly permissive. In an enterprise setting, this may or may not be permissive (e.g. blocking all outgoing traffic except for SFTP on a non-standard port).

LAN_LOCAL is everything inbound to the router from your LAN destined for the router. Again, unless you're doing enterprise routing, this is probably fairly open - although good SMB setups with guest networks may block the guest network range.

Command Auto Completion
You can press the ? key to find the top-level commands, then type that command and ? again to find the options for that top-level command.

? show ? show version show interfaces show interfaces ? show interfaces ethernet

You can also use the keyboard Tab button to complete the options.

Show Configuration
There are 2 ways to show the current configuration - in a tree or in commands:-

show configuration all show configuration commands

If you use the 'commands' option, you can then grep or 'match' the output to limit results.

show configuration commands | match system

Edit Configuration
You have to enter 'edit' mode first, and it will show you after every command that you are in this 'edit' mode with a separate line just above the prompt showing [edit]...

configure

When you have finished your command changes, you can show your changes, to check...

compare

To make the changes active, you have to save them...

commit

Then, come out of configure mode...

exit

Cloud Controller
https://www.stevejenkins.com/blog/2016/05/diy-cloud-hosting-ubiquiti-ubnt-unifi-controller/

Define The Java Version:
Edit the following file, adding the path to Java 8 installation: sudo nano /etc/init.d/unifi JAVA_HOME= # Edit this line to match that shown below JAVA_HOME=/usr/lib/jvm/java-8-oracle

Open The Required Firewall Ports:
Open ports on the server's firewall (in this example UFW):

For internal connection: sudo ufw allow from 192.168.0.0/24 to any port 8080 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 8081 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 8443 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 8843 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 8880 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 27117 proto tcp sudo ufw allow from 192.168.0.0/24 to any port 3478 proto udp

Details of the ports required by Unifi can be found here.

Port 3478 UDP relates to STUN server usage so if you are not using VOIP hardware this port is not needed.

If your server already uses any of the ports listed above how to change those used by Unifi can be found here.

The file to alter to use different ports can be found in the following location:

/usr/lib/unifi/data/system.properties

Accessing The Web Interface:
https://your.server.ip:8443/manage

All being well you should see similar to the picture below:
