New Features

File Compression
Release 2.5 includes improved file compression for internal file storage,
increasing the amount of free space on the flash of the Router Unit. This
allows for larger configuration files stored locally on the flash, and
reduces the frequency of RAS 1500 going into ‘Flash Compaction’ mode.
This feature is automatic and you don’t have to do anything to implement
it.
TCP PAT
Release 2.5 includes support for Port Address Translation (PAT) over the
WAN interface. Transmission Control Protocol (TCP) PAT sets a static
address mapping translation for a connection and associates a user name
with that connection. TCP PAT translates TCP port numbers and user IP
addresses on the private network and maps these addresses to a single
ISP-assigned address.
You can set 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
■
TCP Public Port
■
TCP Private Port
■
TCP Private IP Address
You can also set PAT using CLI. The CLI command for adding TCP PAT
over the WAN interface is as follows:
ADD PAT TCP 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
Parameter
Description
Unique name you assign to the connection that you
want to configure for static TCP PAT.
Limit: 32 ASCII characters.
PRIVATE_ADDRESS
The source IP address of the user on the private
network.
