IP aliasing is associating more than one IP address to a network interface. It allows us to provide multiple network addresses to a single physical base interface. Adding Alias feature gives the base interface another identity. The zone of base interface is the zone of Alias.






Configuring alias IP in Seqrite UTM.

   1. WAN IP: /24

            a) Alias1 IP: /24

            b) Alias2 IP: /24

            c) Alias3 IP: /24 

Note: You must be logged in the Seqrite UTM with admin user with read-write access.

Step 1. Navigating from Functional options

  • Open the Network option in the Left pane.
  • Click the Interface option.
  • Then click Add.

Step 2. Adding Alias interface


Select the Type as Alias.

Alias ID

It is a unique number used to identify the Alias

Alias ID can from 1-255

Note: Alias ID must not be same

Base Interface

It will the physical interface onto which we want to configure the alias.

Note: We can only configure the alias on configured interface


Enter the IPv4 address provided by the Service provider

Subnet Mask

Enter the subnet mask provided by the Service provider

  • Configuring an alias /24 on WAN(eth1) interface of Seqrite UTM.

Note: Do not add IPv4 Gateway for WAN base interface if it is within the same subnet.

  • Similarly we can configure the remaining alias ip addresses.

Step 3. Verification of all alias configuration

Note: In order for the alias to work, the WAN interface must always be green. IP/port forwarding facility can be enjoyed using alias interfaces.
