Authentication
Type
The ZyXEL 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:
CHAP/PAP - Your ZyXEL Device accepts either CHAP or PAP when requested
by this remote node.
CHAP - Your ZyXEL Device accepts CHAP only.
PAP - Your ZyXEL Device accepts PAP only.
Nailed-up
Select Nailed-Up if you do not want the connection to time out.
Idle Timeout
This value specifies the time in seconds that elapses before the ZyXEL Device
automatically disconnects from the PPTP server.

Advanced Setup
Enable NAT
(Network Address
Translation)
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 Direction
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 ZyXEL Device will broadcast its routing table
periodically.
When set to Both or In Only, the ZyXEL Device will incorporate RIP information
that it receives.
When set to None, the ZyXEL Device will not send any RIP packets and will
ignore any RIP packets received.
By default, RIP Direction is set to Both.
