You may define special applications that require multiple connections such

as Internet gaming, video conferencing, and Internet telephony. The BLW-

04EX will then sense the application type and open a multi-port tunnel for

it.

Many advanced applications are provided by the BLW-04EX, such as:

The BLW-04EX provides connectivity to 10/100 Mbps devices, making it

easy to create a network in small offices or homes.

eliminating the need to install this service on your computer.

The BLW-04EX shares a single IP address with up to 253 users. Using only

one ISP account, multiple users on your network can simultaneously browse

the Internet.

If you have a static IP address, you can set up the BLW-04EX to act as a

virtual  host   for  network  address  t ranslat ion.  Rem ote  users  acces s  various

services  at  your  site  using  the  static  IP  address.  Then,  depending  on  the

requested service (or port number), the BLW-04EX routes the request to the

appropriat e  server  (at  an  int ernal  network IP  address).  This  secures  your
