nat timeout time
Minimum Access Level: Administrator
Command Mode: Config
Specifies the NAT timeout value for mappings set up dynamically.
Example: nat timeout 90
time – Specifies the amount of inactive time, in minutes, that can elapse before the
network address translator times out. The default is 20 minutes.
nat napt map { udp | tcp } server-ip port
Minimum Access Level: Administrator
Command Mode: Config
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.
A maximum of 64 static mappings can be created.
Example: nat napt map tcp 192.128.1.1 102
udp, tcp – Specify the protocol used, User Datagram Protocol or Transmission Control
Protocol.
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.
nat basic map public-ip private-ip
nat basic map lower-public-ip lower-private-ip upper-private-ip
Minimum Access Level: Administrator
Command Mode: Config
Statically maps public to private IP addresses for the one-to-one mapping function of
Basic NAT. In the first command, a single address pair is mapped. In the second
command, a range of IP addresses will be contiguously mapped starting at the pair
defined by the lower-public-ip and lower-private-ip argument. A maximum of 64 static
mappings can be created.
Example: nat basic map 192.128.1.1 10.1.3.2
public-ip – IP address of the public address space which is to be mapped to the IP
address of a local host.
private-ip – IP address of a local host which is to be mapped to an IP address in the
public IP address space.
lower-public-ip – Lowermost IP address of a range of public addresses which are to be
mapped to a range of IP addresses of local hosts.
lower-private-ip – Lowermost IP address of a range of local host IP addresses which are
to be mapped to a range of IP addresses in the public IP address space.
upper-private-ip – Uppermost IP address of a range of local host IP addresses which are
to be mapped to a range of IP addresses in the public IP address space.
