Description

This article describes that FortiGate can only allow a maximum of 32 secondary IP addresses per interface.

Scope

FortiGate.

Solution

Sometimes, FortiGate needs to apply multiple secondary IP addresses, especially in the cloud environment.

A maximum of 32 secondary IP addresses can be created for each interface.

The message 'Command fail. Return code -4 (reached the maximum number of entries)' will appear if more than 32 are added.

Enable port forwarding if there are more than 32 internal IP addresses to map.

Note:

The maximum number of secondary IPs on each interface has been extended to 256 on FOS v7.2.4 and later versions.
