The LAN - NAT Menu sets parameters for the NAT address pool for the primary LAN. Network Address Translation
(NAT) is a technique that translates private IP addresses on a private network to valid global IP addresses for access to
another network. Network Address Port Translation (NAPT) translates both the IP address and the port. The advantage of
port translation is that more than one private IP address can be translated to the same single global IP address. NAPT allows
data exchanges initiated from hosts with private IP addresses to be sent to other networks via the P1700 using a single global
IP address. Port translation can also be used from one private network to another private network if the two networks have
conflicting IP addresses.
1 - Translation Type
This option sets the address translation method to be used for NAT. The address may be translated as either a port or an
internal IP address. With IP address translation, each internal IP address is mapped to one global IP address; with port
translation, several internal IP addresses may be mapped to a single global IP address.
Default:
[port]
2 - Dynamic IP Pool
The Dynamic IP Address Pool option defines the block of global IP addresses that may be used to map to internal
addresses. The router will assign a global IP address from this pool to the internal address of a device on the network.
The first address in the range must be specified followed by the number of addresses in the pool.
