Authentication
Method
The VDSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge
Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is
readily available on more platforms.
Use the drop-down list box to select an authentication protocol for outgoing calls.
Options are:
AUTO - Your VDSL Router accepts either CHAP or PAP when requested by this remote
node.
PAP - Your VDSL Router accepts PAP only.
CHAP - Your VDSL Router accepts CHAP only.
MSCHAP - Your VDSL Router accepts MSCHAP only. MS-CHAP is the Microsoft version
of the CHAP.
Enable NAT Select this check box to activate NAT on this connection.
Enable Fullcone NAT This field is available only when you select Enable NAT. Select this check box to
activate full cone NAT on this connection.
Dial on Demand Select this check box to not keep the connection up all the time. Specify an idle time-
out in the Inactivity Timeout field.
Inactivity
Timeout
Specify an idle time-out when you select Dial on Demand. The default setting is 0,
which means the Internet session will not timeout.
PPP IP extension Select this only if your service provider requires it. PPP IP extension extends the service
provider’s IP subnet to a single LAN computer.
• It lets only one computer on the LAN connect to the WAN.
• The public IP address from the ISP is forwarded through DHCP to the LAN computer
instead of being used on the WAN PPP interface.
• It disables NAT and the firewall.
• DHCP tells the LAN computer to use the gateway as the default gateway and DNS
server.
• The VDSL Router bridges IP packets between the WAN and LAN ports except
packets destined for the VDSL Router’s LAN IP address.
Use Static IPv4
Address
Select this option if you have a fixed IPv4 address assigned by your ISP.
IPv4 Address Enter the IPv4 address assigned by your ISP.
Use Static IPv6
Address
Select this option if you have a fixed IPv6 address assigned by your ISP.
IPv6 Address Enter the IPv6 address assigned by your ISP.
Enable IPv6
Unnumbered Model
Select this to enable IPv6 processing on the interface without assigning an explicit IPv6
address to the interface.
Launch Dhcp6c for
Address
Assignment
Select this check box to obtain an IPv6 address from a DHCPv6 server.
The IP address assigned by a DHCPv6 server has priority over the IP address
automatically generated by the VDSL Router using the IPv6 prefix from an RA.
Enable PPP Debug
Mode
Select this option to display PPP debugging messages on the console.
