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 requests from the WAN are translated and sent to this web server.
The Domain Name Server parameters used by the Express 4100/4110 are
specified here. The DNS server addresses can be exchanged between PPP
peers. When a connection occurs and IPCP is negotiated, the Express
4100/4110 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 4100/4110.
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 domain 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.
The Express 4100/4110 can be configured as a relay agent for UDP broad-
cast packets. Normally, a router will not forward UDP broadcast packets.
However, many network applications use UDP broadcasts to configure
addresses, host names, and other information. If hosts using these proto-
