NAT/DHCP Renewal Time
Write security: 3; Read security: 5
This is the number of hours that the DHCP server should allow the device be-
fore 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 Mail server re-
quests from the WAN are translated and sent to this web server.
IP/DNS
The Domain Name Server parameters used by the Express XL/XLT are speci-
fied here. The DNS server addresses can be exchanged between PPP peers.
When a connection occurs and IPCP is negotiated, the Express XL/XLT 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 so requested.
DNS/Domain Name
Write security: 3; Read security: 5
This is a text string used to represent the domain name used by the Express
XL/XLT.
DNS/Server 1
Write security: 3; Read security: 5
This is the IP address for the primary DNS device. It is the first server that do-
main name requests are sent.
DNS/Server 2
Write security: 3; Read security: 5
This is the IP address for the secondary DNS device. It is used a back-up in
case the primary address does not respond to the request.
