The default setting is 180 seconds. The maximum ARP refresh rate is 86400 seconds (24 hours).

Configure Multihome LAN IP Addresses on the Default

VLAN

If you have computers using different IP networks in the LAN, (for example, 172.16.2.0 or 10.0.0.0), you can add aliases to the LAN ports and give computers on those networks access to the Internet, but you can do so only for the default VLAN. The IP address that is assigned as a secondary IP address needs to be unique and cannot be assigned to the VLAN.

It is important that you ensure that any secondary LAN addresses are different from the primary LAN, WAN, and DMZ IP addresses and subnet addresses that are already configured on the UTM.
