ETH IP ADDHOSTMAPPING
Remaps a range of local LAN IP addresses to a range of public IP addresses on a
per-interface basis
. These local
addresses are mapped one-to-one to the public addresses.
Note:
The range of public IP addresses is defined by <
first public addr
> only. The rest of the range is computed
automatically (from <
first public addr
> to <
first public addr
> + number of addresses remapped - 1) inclusive.
ETH IP ADDSERVER
This Network Address Translation (NAT) command is used to add a server’s IP address (on the LAN) associated
with this interface for a particular protocol.

second private addr
Last address in the range of local IP address to be remapped, in the format of 4 decimals
separated by periods.
first public addr
Defines the range of public IP addresses, in the format of 4 decimals separated by periods.
The rest of the range is computed automatically.
port#

last port
If specified, this is used with <
first port
> to specify a range of ports as seen by Ethernet
interface end for the server on the LAN.
