Change Ubiquiti EdgeRouter IP Address

The following steps can be followed to update the public (WAN) IP address and gateway on a Ubiquiti EdgeRouter that has already been configured for service.

1. Plug a computer in to port eth1, eth2, eth3, or eth4 on the front of the EdgeRouter and wait until you receive an IP address
   1. NOTE: You should not be connected to any wireless networks as it may prevent you from accessing the EdgeRouter
   2. The IP address you receive should be in the 192.168.50.x range
2. Open a web browser and go to https://192.168.50.1:8443. Accept any certificate errors and then log in with the username and password
3. Click System tab at the bottom of the page
4. Update the Gateway to the new Gateway address
5. Update the Name Servers to the new Name Server addresses
   1. Leave 8.8.8.8 or 8.8.4.4 if those are listed. All other name server addresses should be updated or removed
      
6. Scroll down and click Save
7. Minimize the System tab if it is still visible so that you are back on the main page
8. Select the Actions dropdown next to interface eth0 and click Config
   
9. Update the IP address to the new IP
   1. NOTE: The IP address you enter must include the full IP, followed by a forward slash and then the CIDR notation for the subnet mask. Use the table below for examples and common CIDR notations.
