8: DNS Configuration (Optional)

Overview

The DNS configuration web pages are setup steps provided for users requiring Inbound Load

Balance.

Domain SOA

In order to make inbound load balance work, the Multi-WAN VPN Link Balancer incorporates a DNS
server module. Users must first construct a server behind the LAN side of the Multi-WAN VPN Link
Balancer. It is also necessary for users to register a domain name with at least two WAN IP addresses
in the “Domain Name Organization” for Static DNS.

Note:

Once you have constructed a server and registered a domain name, you can activate Inbound Load
Balance via the following web page setup:
