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 deÞned by <Þrst public addr> only. The rest of the range is computed
automatically (from <Þrst public addr> to <Þrst public addr> + number of addresses remapped - 1) inclusive.
ETH IP ADDSERVER
This Network Address Translation (NAT) command is used to add a serverÕs IP address (on the LAN) associated
with this interface for a particular protocol.
eth ip addHostMapping <first private addr><second private addr><first public addr><port#>>
Þrst private addr First IP address in the range of local IP address to be remapped, in the format of 4 decimals
separated by periods.
second private addr Last address in the range of local IP address to be remapped, in the format of 4 decimals
separated by periods.
Þrst public addr DeÞnes the range of public IP addresses, in the format of 4 decimals separated by periods.
The rest of the range is computed automatically.
port# Ethernet interface number; can be 0 or 1.
Example:
eth ip addHostMapping 192.168.207.40 192.168.207.49 10.0.20.11 1
eth ip addServer <ipaddr>|discard|me <protocolid> |tcp|udp<first port> |ftp|telnet|smtp|snmp|http [<last port>
[<first private port>]] <port#>
ipaddr IP address of the host selected as server in the format of 4 decimals separated by periods
discard Discards the incoming server request.
me Sends the incoming server request to the local router, regardless of its IP address.
protocolid Protocol used by the selected server; can be tcp or udp.
Þrst port First or only port as seen by the Ethernet interface. Port used by the selected server. Can be a
string such as ftp, telnet, smtp, snmp, or http, or a numeric value between 0 and
65,535. A numeric value of 0 will match any port
last port If speciÞed, this is used with <Þrst port> to specify a range of ports as seen by Ethernet
interface end for the server on the LAN.
Þrst private port If speciÞed, this is a port remapping of the incoming request from the Ethernet interface.
port# Ethernet interface number; can be 0 or 1.
Example:
eth ip addServer 192.168.1.5 tcp smtp 1
eth ip addServer 192.168.1.10 tcp 9000 9000 telnet 0
