The following list, which is not exhaustive, illustrates the standards supported in the
NBG334S.
IP Multicast IP Multicast is used to send traffic to a specific group of computers. The
NBG334S 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 NBG334S itself as the
gateway for each subnet.
Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from
the NBG334S 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 NBG334S supports
one PPTP connection at a time.
Universal Plug and Play
(UPnP)
The NBG334S can communicate with other UPnP enabled devices in a
network.
