PAT CLI Commands
Use the following commands to define static ports for TCP and UDP ports:
add pat tcp
The
add pat tcp
interface
public_port
private_address
public_address
add pat udp
The
add pat tcp
interface
public_port
private_address
public_address
There are some applications which will not work and others that will work if
additional options are configured.
Additional configuration is required to support applications which initiate
connections from a remote host and to support Servers on the local LAN which
have private addresses but can be made accessible from the public network.
Setting the Default
Workstation for
Intelligent PAT
To set the default workstation for Intelligent PAT, perform the following step from
the CLI:
OCG-Adsl>>set nat interface
workstation
workstation ip address> Network Address Translation (NAT) With Network Address Translation (NAT), a pool of public addresses are configured and are statically or dynamically mapped to private workstation addresses when accesses are made through the gateway to a public network. The public to private address mapping remains active until the privately addressed workstation stops accessing the public network. The public address is then returned to the available pool of addresses. When NAT is configured, static mappings and/or dynamic pools of addresses must be configured. Static assignments permanently map a private address to a public address. Dynamic pools consist of a start IP address and an end IP address. Multiple pools can be assigned. Using NetMeeting This section describes how to configure the use of NAT with Microsoft ® NetMeeting. If static NAT Mapping is being used, incoming traffic to the public address of the static NAT policy will go to the private address in the policy. If the private address in the policy is not who the incoming NetMeeting call is intended for, then it will not work.
