DESCRIPTION
The ZyWALL 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:
CHAP/PAP - Your ZyWALL accepts either CHAP or PAP when requested by this
remote node.
CHAP - Your ZyWALL accepts CHAP only.
PAP - Your ZyWALL accepts PAP only.
Select Nailed-Up if you do not want the connection to time out.
This value specifies the time in seconds that elapses before the ZyWALL
automatically disconnects from the PPTP server.
Type the (static) IP address assigned to you by your ISP.
Your ZyWALL will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the subnet
mask computed by the ZyWALL.
Type the IP address of the PPTP server.
Type your identification name for the PPTP server.
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a
public IP address used on the Internet).
Select this checkbox to enable NAT.
For more information about NAT see
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the ZyWALL will broadcast its routing table
periodically.
When set to Both or In Only, the ZyWALL will incorporate RIP information that it
receives.
When set to None, the ZyWALL will not send any RIP packets and will ignore any
RIP packets received.
By default, RIP Direction is set to Both.
