How to Bind a Second IP Address via CLI on Zyxel Devices

Question: How can I bind a second IP address on my Zyxel USG FLEX500 router?

Answer: If you need to add a second IP address on your Zyxel USG FLEX500 router, you can use the CLI (Command Line Interface). This method allows you to manually configure the second IP address, although it won't be visible in the web GUI.

Steps to Bind a Second IP Address via CLI:

1. First, access your device's CLI interface.
2. Run the following commands to configure the second IP address:

                   
                       edit running
                       vrf main interface ethernet
                       ipv4 address [YOUR_SECOND_IP_ADDRESS] [SUBNET_MASK]
                       commit
                       copy running startup
                   
               

3. Replace [YOUR_SECOND_IP_ADDRESS] and [SUBNET_MASK] with your desired IP address and subnet mask.

Note: Even though the second IP address will not show up in the web GUI, you can verify the configuration by checking through the CLI using appropriate commands.

This method provides a solution similar to creating a virtual interface, allowing the use of additional IP addresses for various network requirements, such as separating a phone system network.
