Virtual server
A virtual Server provides a service on the Internet that runs not on itself, but on another
network component. The Gigaset SX763 WLAN dsl can be configured as a virtual server.
It will then direct incoming calls for a service via Port forwarding directly to the appro-
priate Port of the network component in question.
VLAN
Virtual Local Area Network
A VLAN is a virtual local network within a physical network. A widely disseminated tech-
nical implementation of VLANs is defined partially in the Standard IEEE 802.1Q. VLAN
allows preferred forwarding of voice data, for example. This functionality is important
for VoIP (IP telephony). This also means that phone calls can be made without interrup-
tion with a restricted bandwidth.
