Advanced Options (PPPoE)
LLC Header: Select encapsulation mode, true for using LLC or false for using
Create Route: This setting specifies whether a route is to be added to the system after IPCP (Internet Protocol Control Protocol) negotiation is complete. If set to enabled, a route will be created which directs packets to the remote end of the PPP link.
Specific Route: Specify 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: set 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: Set 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: Control 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: Control 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 it gives the DNS server address to the DHCP server instead.
