FIGURE 80 NAT Destination - Add screen
12. Set the following Destination configuration parameters:
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.
Protocol Select the protocol for use with static translation. TCP, UDP and Any are the available options.
Transmission Control Protocol (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.
Destination IP 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.
