2.4.2 Virtual Server
U
se the Virtual Server function when you want different servers/clients in your LAN to handle different service/Internet
application type (e.g. Em
ail, FTP, Web server et
c.) from the Internet. Com
puters use numbers called port numbers to

cognize a particular service/Internet application type. The Virtual Server allows you to re-direct a particular service port
number (fro
m the Internet/WAN Port) to a partic
ular LAN private IP address and its service port number. (See
Glossary
