I have been using EdgeRouter X for about five months now and it is amazing! It has awesome features at an affordable price. Win win situation in my book.
Truth to be told, it is not for average consumer. I am not saying it is difficult to be configured but to benefit fully from it you need to know linux and networking.
For example, you have Port Forwarding and NAT.
You can easily configure port forwarding via "Port Forwarding" but most features you get is if you configure it via "NAT" if you know what you are doing there.
I hope I will have time to prepare another page just for that. It is an interesting journey.
As with all products, it is impossible to have them all so I must mention you cannot use jumbo frames with this one (aka MTU of 9000).
If you attempt to set it up as 9000, the following error will be shown: The max allowed MTU on this platform is 2018.
For me is not a problem but for some of you could be so take that in consideration.
In short, what I like about it is:
1. Linux based (EdgeOS)
2. Easy to use web interface with many options
3. Ssh connectivity to the operating system and not just a set of commands but a full access to the operating system.
You will have to enable this via web management interface.

Having console access can bring you a lot of nice information. For example, the CPU is MIPS 1004Kc.

Before moving forward, I have prepared also a useful tutorial on youtube regarding 7 things I believe you must know how to do:
1. 0:28 - How to connect to it first time and configuration
2. 1:17 - How to change the default password and create/delete users
3. 2:19 - How to set up passwordless connection via SSH
4. 3:16 - Hardware offloading (https://help.ui.com/hc/en-us/articles/115006567467-EdgeRouter-Hardware-Offloading)
5. 4:26 - Firmware upgrade
6. 5:30 - Backup configuration
7. 5:51 - Restore configuration
And if you like written tutorials, following I would like to show you a few command line tricks that you may need.
How to enable hardware offloading:
I have wrote an article about hardware offloading here.
On this device is the same principle: offloading is used to execute functions of the router using the hardware directly, instead of a process of software functions.
Better to check on the support website before deciding if you want this enabled or not: https://help.ui.com/hc/en-us/articles/115006567467-EdgeRouter-Hardware-Offloading.
I have enabled it.
Commands to be executed:
configure set system offload hwnat enable set system offload ipsec enable commit ; save
You will have to reboot in order for changes to take effect.
Output of an execution:
zero@zero:~$ configure  zero@zero# set system offload hwnat enable  zero@zero# set system offload ipsec enable  zero@zero# commit ; save [ system offload ipsec enable ] This change will take effect when the system is rebooted. WARNING : IPsec offload on ER-X platform is causing problems to L2TP remote-access VPN. and IPV6 site-to-site IPSec VPN You should *not* enable IPsec offload if you are using any of above. Other VPN modes are not affected by this issue: * IPv4 site-to-site IPsec VPN is working correctly with IPsec offload. * PPTP VPN is working correctly with IPsec offload. Only ER-X/ER-X-SFP/EP-R6 models are affected by this issue. This issue is to be fixed in future release. Saving configuration to '/config/config.boot'... Done  zero@zero#
Update the boot loader after firmware upgrade:
In short, bootloader controls some functions like LED boot behavior, configuration/driver loading and so on and this on most EdgeRouter models is not updater automatically and it must be done manually.

Command to execute:
add system boot-image

How to add ssh key on your EdgeRouter (min 2:19 in the video above):
Commands to be executed:
NOTE: replace KEY with the actual key you want to add :)
