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.

16. Select the Dynamic NAT
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 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.
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.
Select Inside or Outside NAT as the network direction. The default setting is Inside.
Select Inside to create 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. Inside NAT is the default setting.
