The following list, which is not exhaustive, illustrates the standards supported in the
NBG334W.
NBG334W.
IP Multicast
IP Multicast is used to send traffic to a specific group of computers. The
NBG334W supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias
IP Alias allows you to subdivide a physical network into logical networks
over the same Ethernet interface with the NBG334W itself as the
gateway for each subnet.
Logging and Tracing
Use packet tracing and logs for troubleshooting. You can send logs from
the NBG334W to an external UNIX syslog server.
PPPoE
PPPoE mimics a dial-up over Ethernet Internet access connection.
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of
data through a Virtual Private Network (VPN). The NBG334W supports
one PPTP connection at a time.
Universal Plug and Play
(UPnP)
The NBG334W can communicate with other UPnP enabled devices in a
network.
