New virtual interfaces can be made for use with private ports by clicking Administration - Targets -
Port Configuration - Network Settings. For more information on creating an interface, see Port
configuration on page 50.
Interfaces Tab
From the Interfaces tab you designate interfaces as either inside or outside, with respect to how
they will be used within NATand firewall rules. Interfaces designated as Inside are private and
interfaces designated as Outside are public.
Be sure to designate at least one interface as Outside and one interface as Inside before trying to
reference those interfaces within a NATor firewall rule. When network mode changes or interface
name changes occur, this table must be updated to ensure the proper interface is designated as
Inside or Outside. Also ensure that IPaddresses are correctly resolved in the tables at the bottom
of the screen. If IPaddresses are not correct, move them from the included list to the available list
and back again to refresh the data within the table.
To move an interface:
1. From the sidebar, click Firewall and NAT, then click the Interfaces tab.
2. Under the Outside i/f (Public)or the Inside i/f (Private)heading, click an interface you want to
move from the Available field, then click the Right Arrow to move it to the Include field.
