C-194 User's Reference Guide
Exported services are configured under IP Setup in System Configuration. This is where a particular type of TCP
or UDP service originating from the Internet is redirected to a host on the Netopia R910's LAN interface. An
example of this screen follows:
Service...
Local Server's IP Address:
Within exported services is a pop-up list of well-known TCP and UDP services that can be redirected to a single
host on the Netopia R910's LAN interface. There is also an "Other..." option that allows for manual
configuration of additional TCP or UDP ports. There can be a total of 32 exported services that can be defined.
When a particular type of service is redirected to an IP address, that service is removed from the pop-up list,
since only one type of service can be redirected to a single host. However several different types of services
can be redirected to a single or multiple hosts. For example, port 80 (WWW server) could be redirected to
192.168.5.3 on the Netopia R910's LAN interface, and port 23 (Telnet) can be redirected to that same host.
Summary
NAT is a powerful feature of the Netopia R910 and when used and set up properly can yield a secure network
while only using one IP address on the WAN interface. Note that the addresses listed in this appendix are for
demonstration purposes only. Do not use these addresses when configuring your local network.
