Static NAT creates a permanent, one-to-one mapping between an address on an internal network and a
perimeter or external network. To share a Web server on a perimeter interface with the Internet, use
static address translation to map the actual address to a registered IP address. Static address translation
hides the actual address of the server from users on insecure interfaces. Casual access by unauthorized
users becomes much more difficult. Static NAT requires a dedicated address on the outside network for
each host.

Dynamic NAT configurations translate the IP address of packets going out from one interface to another
interface based on configured conditions. Dynamic NAT requires packets be switched through a NAT
router to generate translations in the translation table.

Destination configuration parameters:
Select the protocol for use with static translation. TCP, UDP and Any are
available options. TCP is a transport layer protocol used by applications
requiring guaranteed delivery. It's a sliding window protocol handling both
timeouts and retransmissions. TCP establishes a full duplex virtual
connection between two endpoints. Each endpoint is defined by an IP
address and a TCP port number. The User Datagram Protocol (UDP) offers
only a minimal transport service, non-guaranteed datagram delivery, and
provides applications direct access to the datagram service of the IP layer.
UDP is used by applications not requiring the level of service of TCP or are
using communications services (multicast or broadcast delivery) not
available from TCP. The default setting is Any.
Enter the address used at the (source) end of the static NAT configuration.
This address (once translated) will not be exposed to the outside world
when the translation address is used to interact with the remote
destination.
Use the spinner control to set the local port number used at the (source)
end of the static NAT configuration. The default value is port 1.
Enter the IP address of the matching packet to the specified value. The IP
address modified can be either source or destination based on the
direction specified.
Enter the port number of the matching packet to the specified value. This
option is valid only if the direction specified is destination.
