NAT/DHCP Renewal Time
Write security: 3; Read security: 5
This is the number of hours that the DHCP server should allow the de-
vice before it is required to send a new DHCP request. The default is
15 hours, and 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, communication across NAT must be initiated
from the LAN side of the Express L768. 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 Express L768 for Network Address
Translation when nothing is assigned during the PPP negotiation
when PPP mode is active or when nothing is specified in the DLCI
Mapping's Link IP Address.
»» IP/DNS
The Domain Name Server parameters used by the Express L768 are
specified here. The DNS server addresses can be exchanged between
PPP peers. When a connection occurs and IPCP is negotiated, the Ex-
press L768 will get the DNS server addresses from the PPP peer. If the
configured DNS server addresses (Server 1 and Server 2) are all zeros,
the addresses from the PPP peer are used. In NAT mode, the PPP
peer's DNS addresses are always used. The DNS addresses set in Server
1 and Server 2 are offered to a PPP peer if requested.
