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-addr ip-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
