Network Address Translation for Alarm Stations

In a nutshell

A connection to one or many Multi-Media alarm stations, using one IP address, can be made by using network address translation (NAT) and port address translation (PAT)—a one-to-many address translation. This is useful to connect to alarm stations through:

•A WAN

•The Internet

•To another segment of the same LAN.

IP Addresses

The key is to configure a router to translate and map the Callbacks source IP port. The Network Administrator of the destination’s LAN can supply a Multi SA with the “Outside” IP address of the internet router.

IP Port

Callbacks to alarm stations on a remote LAN are identified by the value of the Callback Source IP Port box, in the Add Alarm Station /Update Alarm Station dialog boxes of Admin software, shown in figure 11–4.Each alarm station on a remote LAN needs to have a different Callback value.

Mapping IP port in network’s router

For each Multi-Media alarm station, one port mapping is needed when translating a network address.
