DESCRIPTION
The Device 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 Device accepts either CHAP or PAP when requested by
this remote node.
PAP - Your Device accepts PAP only.
CHAP - Your Device accepts CHAP only.
MSCHAP - Your Device accepts MSCHAP only. MS-CHAP is the
Microsoft version of the CHAP.
Select this check box to activate NAT on this connection.
Select this check box to activate full cone NAT on this connection.
This field is available only when you select Enable NAT.
Select this check box to activate the firewall on this connection.
Select this check box when you do not want the connection up all the
time and specify an idle time-out in the Inactivity Timeout field.
Specify an idle time-out when you select Dial on Demand. The
default setting is 0, which means the Internet session will not timeout.
Select how the WAN interface is to get its IP address.
• Dynamic IPv4 Address: Has the Device get an IP address
automatically from the PPPoE or PPPoA server.
• Static IPv4 Address: Select this if your ISP provided a single
static IP address for you to use. Then enter the static IP address
provided by your ISP in the IPv4 Address field that displays.
• Unnumbered Mode: Select this if your ISP provided a range of
static public IP addresses for you to use.
Enter the Device's WAN IP address and subnet mask in the
Gateway IP address and Subnet Mask fields that display. The
subnet mask must be smaller than C class (255.255.255.0).
Select Assign Public IP to LAN PCs by DHCP to have the Device
give the LAN DHCP clients public IP addresses. LAN clients can still
configure static private IP addresses and access the Internet.
Clear the Assign Public IP to LAN PCs by DHCP option to assign
the LAN DHCP clients private IP addresses. LAN clients can still
configure static public IP addresses and access the Internet.
Select this option if you want to have the Device use the IPv6 prefix
from the connected router's Router Advertisement (RA) to generate
an IPv6 address.
Select this checkbox if you want 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 Device using the IPv6 prefix
from an RA.
Select this option if you have a fixed IPv6 address assigned by your
ISP.
