Technical Tip: Unable to configure gateway address using network address after upgrade to v7.2.4

To solve this issue, configure a different IP Address range/subnet on the interface first before configuring the static route then modify the interface IP Address to the actual or original value.

Port3 IP Address configuration.

Configuring a static route using a network object will throw an error 'Invalid Gateway Address'.

Configure the IP Address of port3 to be in a different subnet or network than the Gateway Address in the static route. 

Change the IP Address of port3 from 192.168.2.2 to 192.168.3.2.

After configuring a different network in port3, there’s no more error message shown when configuring the network address 192.168.2.0.

Change the IP Address (192.168.2.2) on port3 back to its original value.

Verify the configuration in CLI.

Iriz-kvm46 # show system interface | grep -f port3

config system interface

    edit "port3" <---

        set vdom "root"

        set ip 192.168.2.2 255.255.255.240

        set type physical

        set snmp-index 3

    next

end

Iriz-kvm46 # show router static | grep -f port3

config router static

    edit 2

        set gateway 192.168.2.0

        set device "port3" <---

    next

end
