Fill out the screen using the following parameter definitions:
• Detection of WAN failure—WAN failure is detected using DNS queries to the DNS
server. For each WAN interface, DNS queries are sent to the configured DNS server. If the
DNS replies are not received, the corresponding WAN interface is considered down.
– ISP DNS Server—In this case, DNS queries are sent to the DNS server configured on
the WAN ISP pages (see
“Step 3: Configure the Internet Connections to Your ISPs
(Required)” on page 4-8 ).
– Public DNS Server—The user is also given an option to enter any Public DNS server.
DNS queries are sent to this server through the WAN interface being monitored.
