Configure virtual IP addresses

Virtual IP addresses are used to configure multiple IP addresses from different subnets (including private addresses) on a single network interface.

Example of creating a Virtual IP as a secondary IP.

1. Create Virtual IP.
2. Check the cohesiveness.

Create Virtual IP⁠

1. В graphical interface from the main menu, go to Firewall → Virtual IPs.

2. Click Add.

3. Enter the basic parameters for Virtual IP:

   • Type — IP Alias;
   • Interface — the network interface on which the configuration is being performed;
   • Address(es) — The IP address that is used as the secondary IP.

4. Click Save.

5. Click Apply Changes to apply the configuration.

Check cohesion⁠

1. В graphical interface from the main menu, go to Diagnostics → Ping.

2. Enter the network interface parameters of one of the devices:

   • Hostname — IP address;
   • IP Protocol;
