Introduction
This article describes how to create and configure a network object for port redirection or port forwarding over a specific IP when multiple public IP addresses are present.
Port redirection or port forwarding is applied only to the smallest IP address on a network object.
Consequently, in order to be applied specifically to another IP address, it is necessary to set up additional network objects:
Scenario:
Assigned network: 198.51.100.48/29
IP address 1: 198.51.100.49/29
IP address 2: 198.51.100.50/29
Preparation
Edit interface UTMuser@firewall.name.fqdnNetworkNetwork Configuration Network Network configuration Area Network interfaces Button → IP Addresses The IP addresses on the interface must be entered here
Create a new network object
Create a new network object with Firewall Network objects Area Add object Button +
Search for the network object external-interface and click the button

The external interface must be edited so that it only affects this IP in further, general rules and does not inadvertently provide the other IP with rules.
Address:
198.51.100.49/32
Entry of the 1st IP address on the existing interface (change to suffix with tab key)
Existing address 0.0.0.0/0 applies to all IP addresses!
