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.
NAT rules
The following rules apply to assigning NAT ranges and ser ver lists:
■ Static public address ranges must not overlap other static, PAT, public addresses, or the public address
assigned to the router’s WAN inter face.
■ A PAT public address must not overlap any static address ranges. It may be the same as another PAT
address or ser ver list address, but the por t range must not overlap.
You configure the ranges of exterior addresses by first adding public ranges.
Select Add Public Range and press Return.
