Authentication Protocol: Default is Chap(Auto). Your ISP will advise you whether to use Chap or Pap.
Connection:
Always on: If you want the router to establish a PPPoE session when starting up and to
automatically re-establish the PPPoE session when disconnected by the ISP.
Connect on Demand: If you want to establish a PPPoE session only when there is a packet
requesting access to the Internet (i.e. when a program on your computer attempts to access the
Internet).
Idle Timeout: Auto-disconnect the broadband firewall gateway when there is no activity on the line for a
predetermined period of time.
Detail: You can define destination port and packet type (TCP/UDP) information that will not
result in the router checking the timer. It allows you to set which outgoing traffic will not trigger
and reset the idle timer.
RIP: RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
MTU: Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers)
that the IP will attempt to send through the interface.
Advanced Options (PPPoE)
LLC Header: Selects encapsulation mode. Select true to use LLC or false to use VC-Mux.
Create Route: This setting specifies whether a route is added to the system after IPCP (Internet Protocol
Control Protocol) negotiation is completed. If set to enabled, a route will be created which directs packets to
the remote end of the PPP link.
Specific Route: This specifies whether the route created when a PPP link comes up is a specific or
default route. If set to enabled, the route created will only apply to packets for the subnet at the remote
end of the PPP link. The address of this subnet is obtained during IPCP negotiation.
Subnet Mask: This sets the subnet mask used for the local IP interface connected to the PPP transport.
If the value 0.0.0.0 is supplied, the netmask will be calculated from the class of the IP address obtained
during IPCP negotiation.
Route Mask: This sets the subnet mask used by the route that is created when a PPP link comes up. If it is
set to 0.0.0.0, the subnet mask is determined by the IP address of the remote end of the link. The class of
the IP address is obtained during IPCP (Internet Protocol Control Protocol) negotiation.
MRU: Maximum Receive Unit. This is negotiated during the LCP protocol stage.
Discover Primary / Secondary DNS: This setting enables/disables whether the primary/secondary DNS
server address is requested from a remote PPP peer using IPCP. The default setting for this command is
enabled.
Give DNS to Relay: This controls whether the PPP Internet Protocol Control Protocol (IPCP) can
request the DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP
address, it automatically gives the address to the local DNS relay so that a connection can be
established.
Give DNS to Client: This controls whether the PPP Internet Protocol Control Protocol (IPCP) can
request a DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP
address, it automatically gives the address to the local DNS client so that a connection can be
established.
Give DNS to DHCP Server: Similar to the above, but gives the DNS server address to the DHCP server.
Discover Primary NBNS / Discover Secondary NBNS: This setting enables/disables whether the
primary/secondary NBNS server address is requested from a remote PPP peer using IPCP. The default
setting for this command is disabled.
Discover Subnet Mask: Specifies if the subnet mask given by IPCP negotiation process is to be used.
Give Subnet Mask To DHCP Server: Enable to change your DHCP Server settings by using the given
information in IPCP negotiation process.
