Overview

 

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.

       

Applicable Version: All

                                                                                                                        Scenario            

Configuration

 

Configuring alias IP in Seqrite UTM.


   1. WAN IP: 1.22.124.221 /24

            a) Alias1 IP: 1.22.124.222 /24

            b) Alias2 IP: 1.22.124.223 /24

            c) Alias3 IP: 1.22.124.224 /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


 

Type              

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

IPv4

Enter the IPv4 address provided by the Service provider

Subnet Mask

Enter the subnet mask provided by the Service provider

  • Configuring an alias 1.22.124.222 /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.
