RIP/V2 Secret
Write security: 0; Read security: 0
This is a text string used for authenticating advertised routes.
IP/NAT
The Network Address Translation general parameters are set up
under this menu.
NAT/DHCP Mode
Write security: 3; Read security: 5
When this option is set to On, the Router Option Module acts as a
DHCP server and will dynamically assign IP, network mask, de-
fault gateway, and DNS addresses to any device which transmits a
broadcast DHCP request. The addresses assigned are based on the
Router Option Module’s own IP address and will be within the
same network. This mode is most commonly used with the NAT
functionality. The default is Off.
NAT/DHCP Renewal Time
Write security: 3; Read security: 5
This is the number of hours that the DHCP server should allow the
device before it is required to send a new DHCP request. The default
is 15 hours. Zero (0) represents an infinite lease.
NAT/Web Server
Write security: 3; Read security: 5
This is the IP address of a web server on the Ethernet network.
When an active NAT connection is made to the Internet, any HTTP,
FTP, or SMTP server requests from the WAN are translated and sent
to this web server.
Normally, communications across NAT must be initiated from the
LAN side of the Router Option Module. Web server allows a single
machine on the NAT side to be accessed from the Internet side of
NAT. This provides outside access to a Web server, mail, or FTP
server.
NAT/Default IP
This is the IP address used by the Router Option Module for Net-
work Address translation when nothing is assigned during the PPP
negotiation when PPP mode is active or when nothing is specified
in the DLCI Mapping Link IP Address.
