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 R5000 Series Router's LAN interface. There is also an Other... option that allows for
manual configuration of additional TCP or UDP ports. You can define a total of 32 exported services.
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 R5000 Series Router's LAN interface, and port 23 (Telnet) can be redirected to
that same host.
NAT is a powerful feature of the Netopia R5000 Series Router 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.
