It is possible to run internet facing services such as email and web from servers on your internal network by setting up an IP Mapping. Each Control Zone account receives
a complimentary internet IP address that can be used to map ports to internal IPs at any of your sites. Additional internet IP addresses can be automatically assigned to your account
by requesting them under your licensing configuration.
Several different types of failover detection can be setup for a mapping, and up to three IPs at your sites can be specified for the mapping to failover to in the event of
one of your servers becoming unavailable.
