UDP PAT
Release 2.5 includes support for User Data Protocol (UDP) PAT over the
WAN interface. UDP PAT sets a static address mapping translation for a
connection and associates a user name with that connection. UDP PAT
translates UDP port numbers and user addresses on the private network
and maps these addresses to a single ISP-assigned address by changing
the source IP port number and IP address.
You can set UDP PAT through the Web Configuration Interface. From the
main, browser-based Web Configuration Interface page, click
Select
NAT/PAT Configuration
under the
Network
menu, choose PAT and
supply the following parameters:
■
User name
■
UDP Public Port
■
UDP Private Port
■
UDP Private IP Address
You can also set UDP PAT using CLI. The CLI command for adding UDP
PAT over the WAN interface is as follows:
ADD PAT UDP USER
This command should be followed sequentially by the following sub
commands. See the table below for definitions of the parameters.
PRIVATE_ADDRESS
PRIVATE_PORT
PUBLIC_PORT
PRIVATE_PORT
The source port number on the private network from
which TCP packets are transferred.
PUBLIC_PORT
The destination port number of the ISP-assigned IP
address on the public network.
