11 Remote Management Functions

One of the problems with IP networking that the IRIS system solves is how to

make a remote management call into the IRIS dialler or the attached alarm

panel when the dialler is on a private network behind a router that is the

gateway to the public Internet.

Such as situation is very common, ranging from very big networks (e.g. a

retailer’s network with hundreds of sites) to very small networks (e.g. a home

network with an ADSL line and a couple of PCs).

This is illustrated below:

The IP addresses within the private network are allocated automatically

(dynamically by DHCP). The IP addresses externally are fixed public IP

addresses.
