Command Line Interface

NAT

nat basic enable

Enables the one-to-one mapping function of Basic NAT. Enabling Basic NAT automatically disables NAT NAPT. If Basic NAT is enabled, Proxy ARP must be enabled on the dsl1 interface when the dsl1 interface address is part of the Basic NAT global IP network address.

Minimum access level: Administrator/Config

nat napt enable

Enables the many-to-one mapping function of NAPT. Enabling NAT NAPT automatically disables Basic NAT.

Minimum access level: Administrator/ Config

NOTE: Proxy ARP and NAPT cannot be enabled at the same time.

nat basic address ip-addr[ip-mask]

Defines the public IP addresses used in the one-to-one mapping function of Basic NAT

Up to 256 addresses can be allocated with Basic NAT.

Minimum access level: Administrator/Config

ip-addrip-mask± Any valid public IP address/IP mask. Default = 255.255.255.0.

Example: nat basic address 192.128.1.1

nat napt address ip-addr

Defines the public IP addresses used in the public IP address of a single host for use in the many to one mapping function of NAPT. NAPT cannot accept incoming requests, unless a static NAT entry has been configured.

Minimum access level: Administrator/Config

ip-addr± Any valid public IP address.

Example: nat napt address 192.128.1.1

nat timeout time

Specifies the NAT timeout value for mappings set up dynamically.

Minimum access level: Administrator/Config

time ± The timeout value in minutes. Default = 20 minutes.

Example: nat timeout 90

nat napt map { udp tcp } server-ip port

Permits global access to a local server, such as a Web server. Port-based static entries can be configured for NAPT. This allows a global host to access a server behind the DSL router without exposing the local server's IP address.

Minimum access level: Administrator/Config

udp, tcp ± Specify the protocol to which the mapping applies.

server-ip± Enter the IP address of a local server. Only one server of a particular type (FTP, Telnet, SMPT, TFTP, gopher, finger, http, etc.) can be supported at one time.

port ± The destination port number for the specified server.

Example: nat napt map tcp 192.128.1.1 102
