Internal users can access the Internet as they always do; the external Internet, however, views all traffic from
the internal network as originating from 192.168.100.6 and all traffic your network receives is addressed to
192.168.100.6.
When an IP client such as a Netscape Navigator or Microsoft Internet Explorer wants to establish a session with
an IP server such as a Web server, the client machine must know the IP address to use and the TCP service
port where the traffic is to be directed.
For example, a Web browser locates a Web server by using a combination of the IP address and TCP port that
the client machine has set up.
Just as an IP address specifies a particular computer on a network, ports are addresses that specify a
particular service in a computer. There are many universally agreed-upon ports assigned to various services.
For example:
Web servers typically use port number 80
All FTP servers use port number 21
Telnet uses port number 23
SNMP uses port number 161
To help direct incoming IP traffic to the appropriate server, the Netopia R5000 Series Router lets you associate
these and other port numbers with distinct IP addresses on your internal LAN using the feature called exported
services. See "IP setup" on page 9-12
