subscribers to connect to Internet Service Providers.
Select the IP Address option PPPoE to configure a PPPoE tunnel in order to connect to an ISP.
Only the external network interface can be configured as PPPoE client as all the traffic will be sent via this
tunnel. The IP address, Default gateway IP and DNS server IP address will be obtained from the PPPoE
server after PPPoE connection is established. Broadcast address is used for the PPPoE server discovery
and tunnel establishment.
Valid authorization credentials are required for the PPPoE connection:
PPPoE Username
– username to connect to the server (must match the configured on the
PPPoE server);
Password
– password to connect to the server (must match the configured on the PPPoE server);
PPPoE MTU/MRU
– the size (in bytes) of the Maximum Transmission Unit (MTU) and Maximum Receive
Unit (MRU) used for the data encapsulation while transferring it through the PPP tunnel;
Enable DMZ: The Demilitarized zone (DMZ) can be enabled and used as a place where services can be
placed such as Web Servers, Proxy Servers, and E-mail Servers such that these services can still serve
the local network and are at the same time isolated from it for additional security. DMZ is commonly used
with the NAT functionality as an alternative for the Port Forwarding while makes all the ports of the host
network device be visible from the external network side.
DMZ Management Port: Web Management Port for the based device (TCP/IP port 80 by default) will be
used for the host device if DMZ Management Port option is enabled. In this case device will respond to
the requests from the external network as if it was the host which is specified with DMZ IP. It is
recommended to leave Management Port disabled while the based device will become inaccessible from
the external network if enabled.
DMZ IP: connected to the internal network host, specified with the DMZ IP address will be accessible
from the external network.
With a multicast design, applications can send one copy of each packet and address it to the group of
computers that want to receive it. This technique addresses packets to a group of receivers rather than to
a single receiver. It depends on the network to forward the packets to the hosts which need to receive
them. Common Routers isolate all the broadcast (thus multicast) traffic between the internal and external
networks, however provides the multicast traffic pass-through functionality.
