in the Default Port-based VLAN ID field. This field is only required when port-based VLANs are
enabled, and must be unique amongst the VLANs on this switch. If a port is disabled for all VLANs, then
the port will be set to untagged mode for the default VLAN. The untagged mode means the VLAN ID will
only be used while routing packets within this appliance. Devices connected to ports on the default VLAN
will not see the VLAN ID on the packet, and do not need to support VLANs. Therefore the actual value is
irrelevant, as long as it is unique.

Aliases tab

Alias addresses are typically assigned to an Internet network connection. Alias addresses enable you to use
the same TCP or UDP port for multiple servers. Interface aliases allow the UTM Firewall appliance to
respond to multiple IP addresses on a single network interface. This is useful for when your ISP has
assigned you a range of IP addresses to use with your Internet connection, or when you have more than
one subnet connected to a single network interface.
Figure 39 Aliases tab
For aliases on interfaces that have the DMZ or Internet firewall class, you must also setup appropriate
packet filtering or port forwarding rules to allow traffic on these ports to be passed from the alias address to
servers on the local network. For details, see
