NOTE:
ww.xx.yy.zz is the IP address that the user on the local LAN assigns.
Server Configuration
This section is intended for users and network administrators who wish to allow WAN
access to a Web server, FTP server, SMTP server, etc., on their local LAN, while
using NAT.
NAT needs a way to identify which local PC [local IP address(es)] should receive
these server requests. The servers can be configured on a per-remote-router and per-
Ethernet-interface basis as well as globally.
Interface-Specific Commands
You can specify servers for specific remote interfaces and for specific Ethernet
interfaces. Servers can also be designated for specific protocols and ports. To enable
and disable a local IP address (on your LAN) as the server for a specific remote
interface, use the following commands:
-> remote addserver <action> <protocol> [<last port> [<first
private port>]] <remotename>
-> remote delserver <action> <protocol> [<last port> [<first
private port>]] <remotename>
To see all of the remote entries, use the command:
-> remote list <remotename>
To enable and disable a local IP address (on your LAN) as the server for a specific
Ethernet interface, use the following commands:
-> eth ip addserver <action> <protocol> [<last port> [<first
private port>]] <interface>
-> eth ip delserver <action> <protocol> [<last port> [<first
private port>]] <interface>
NOTE:
Enter a save command to make the changes persistent across reboots.
Example 1
Assume that the local LAN network is 192.168.1.0 255.255.255.0. The following
commands enable a Telnet server on the local LAN with the IP address 192.168.1.3,
and an FTP server with the IP address 192.168.1.2.
-> remote addserver 192.168.1.3 tcp telnet router1
