The Network Address Translation screen appears.

Public Range

defines an external address range and indicates what type of mapping to apply when using this

range. The types of mapping available are

dynamic

,

static

and

pat

.

Map Lists

define collections of mapping rules. A rule maps interior range addresses to exterior range

addresses by the mapping techniques defined in the map list.

Server Lists

bind internal IP addresses and por ts to external IP addresses and por ts so that connections

initiated from the outside can access an interior ser ver.
