Architecture with IP sharing device

7-1.1 Virtual Servers on the IP sharing device

For the most part, IP sharing devices act as clients, not as servers. However, if you want to

install servers such as web, mail or devices like the IPP unit on the LAN side, you must configure

such devices as virtual servers with the IP sharing device. The IPP unit behaves as a server, so you

must configure the IP sharing device to treat it as a virtual server.

Every server uses a particular port (e.g. TCP port 80 for Web servers and TCP port 21 for FTP

servers). The IPP unit uses UDP port 2000. The method used to configure a virtual server is to map

the server port to the private IP that the virtual server is assigned. Thus is so that incoming packets

that are meant to reach a particular server port are correctly forwarded to the server’s assigned

private IP address on the LAN side of your network. For example, if you want to install a web

server on the LAN side of your network using a private IP address (e.g.192.168.1.1), you must

configure the correct port mapping on the IP sharing device so that it is able to forward all packets

that are intended for destination port TCP 80 on the server’s assigned private IP address

(e.g.192.168.1.1:80). The mapping should be as follows: TCP port 80 <-> 192.168.1.1.
