3 Features

3.1 Network connections

Watson SHDSL router supports various network connections. Besides the physi-

cal LAN and WAN connections, other logical connections, using tunneling proto-

cols over existing connections, such as PPP and VPN can be configured.

Every network connection in Watson SHDSL router can be configured as one of

three types: WAN, LAN or DMZ. This provides high flexibility and increased func-

tionality.

For example a network connection can be defined as a DMZ (Demilitarized) net-

work. Although the network is physically inside Watson SHDSL router, it will

function as an unsecured, independent network, for which Watson merely acts

as a router.

3.1.1 Bridging

With the network bridging feature several network connections can be combined

together under one virtual network.

For example, creating one network for LAN Ethernet and WAN Ethernet devices.

3.1.2 Routing

Watson SHDSL router can be setup to use static or dynamic routing. Dynamic

routing automatically adjusts how packets travel on the network, whereas static

routing specifies a fixed routing path to neighboring destinations.

Watson SHDSL router supports two different routing modes:

In ROUTE mode Watson functions as a router between two networks.

In NAPT mode Watson performs Network Address and Port Translation. NAPT

refers to network address translation involving the mapping of port numbers, al-

lowing multiple machines to share a single IP address. NAPT should be used if

the LAN encompasses multiple devices, a topology that necessitates port trans-

lation in addition to address translation.
