NAT IP

Source NAT 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 (internal) 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 (internal) 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.
