So there you have it, a device that can handle multiple computers/users online without being speed limited by a single Cable/DSL channel. The NetPassage router automatically divide the bandwidth of the multiple channels. All NetPassage 15B series are equipped with a RJ45 Ethernet port for external Cable/ADSL modem (WAN), Furthermore integrated we can find a a 4-port 10/100Mbps (LAN) Fast Ethernet Switch, when you hook up some hubs or Switches you can actually support a maximum of 253 users. This internal built-in Switch is also designed with an auto-crossover mechanism which detects the orientation of the UTP cable (whether straight or crossover) for Uplink connection. The 15B automatically assigns IP addresses and gateway information to the workstations, making the network configuration a quick and easy process. It is also capable of translating a single public IP to multiple private IP addresses, enabling access from one Broadband Internet account to be distributed to multiple workstations. Additionally, the NetPassage 15B is also designed with the ability to define Virtual Servers. Two types of Virtual Servers can be implemented with NetPassage 15B series – IP Mapping and TCP/UDP Port Mapping. During the test-fase of this product we where able to host dedicated Counter-Strike servers and Unreal Tournament servers without too many problems. Last but no least the 15B provides network administration such as Virtual Server and IP Packet Filtering which is used to assign different access period to different group of users. Internet applications not preferred by the network administrators can also be blocked. All of this is configured by an easy to use and handle web based interface to the router.

To understand the router let's take a look at some definitions on what it a router exactly does, is integrated and what technology you need to understand a threefold of items.

Routing - In its simplest form a router is a gateway between multiple PC's and directs the proper (TCP/IP) information towards the specific PC, thus it will share your internet connection. Any router has a LAN and a WAN port. LAN is you Local Network, WAN of course is the Wide Area Network that you are connected to. Routers work much like bridges, but they pay attention to the upper network layer protocols (OSI layer 3) rather than physical layer (OSI layer 1) protocols. A router will decide whether to forward a
packet by looking at the protocol level addresses (for instance, TCP/IP addresses) rather than the MAC address. Because routers work at layer 3 of the OSI stack, it is possible for them to transfer packets between different media types (i.e., leased lines, Ethernet, token ring, X.25, Frame Relay and FDDI). Many routers can also function as bridges.
