DNS Configuration
This page shows the active run-time settings for the domain name system (DNS)
protocol. The primary and secondary DNS addresses come from the active interface.
The static addresses from the Network Interface Configuration page may be
overridden by DHCP or BOOTP.
The DNS page also shows any contents in the DNS cache. When a DNS name is
resolved using a forward lookup, the results are stored in the DNS cache temporarily.
The XPort Pro consults this cache when performing forward lookups. Each item in
the cache eventually times out and is removed automatically after a certain period, or
you can delete it manually.
To view the XPort Pro DNS configuration:
Click DNS on the menu bar. The DNS page appears.

PPP Configuration
Point-to-Point Protocol (PPP) establishes a direct connection between two nodes. It
defines a method for data link connectivity between devices using physical layers
(such as serial lines). For more information about PPP, see
13 Point to Point
Protocol PPP
.
The XPort Pro supports two types of PPP authentication: Password Authentication
Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP). Both of
these authentication methods require the configuration of a username and password.
