Configuring Static
PAT Port Entries
Press the Static Transmission Control Protocol (TCP) or Static User
Data Protocol (UDP) button to access the static port tables.
■
Static TCP — Press this button to access the static PAT TCP table
(above). Using this table, you can map public TCP ports to private IP
address / TCP port pairs.
This is useful for controlling access to the LAN by remote users. For
example, an entry containing public TCP port 80, the IP address of a
web server on your LAN, and the private TCP port 80 allows controlled
access to the web server but not the rest of your LAN. (For a list of
assigned port numbers, see RFC-1700, Assigned Numbers document
which is available from the Internet.)
■
Static UDP — Press this button to access the static PAT UDP table
(above). Using this table, you can map public UDP ports to private IP
address / UDP port pairs. This is useful for controlling access to the
LAN by remote users. (For a list of assigned port numbers, see
RFC-1700, Assigned Numbers document which is available from the
Internet.)
