5.0 Networking
There are many factors involved in setting up the Network Communication on a DoorsNXT installation.
Some data will need to be provided by a Network Administrator familiar with the network where the
DoorsNXT is to be installed. The main factors to consider when setting up the network are:
• Location of the controllers and Subnet configuration
• Network Security and Firewalls
Figure 14: Setup Networking
5.1 Location and Subnet Configuration
DoorsNXT can communicate to controllers on the local subnet or networks outside of the local subnet
using the DoorsNXT Proxy. The Subnet Data (below) will differ for each subnet. Each controller is
configured with a Subnet Property that consists of a Subnet Name, Proxy IP Address, Gateway Address,
and Subnet Mask.
By default DoorsNXT is configured with a single Subnet Property: Local Subnet. This subnet
communicates to the LAN connected to the DoorsNXT Server. There is no Proxy IP Address associated
with the Local Subnet since it is not needed. The Local Subnet property cannot be deleted, but it can be
disabled if necessary.
DoorsNXT can have multiple Subnet properties defined. To modify the local subnet property or create a
new Subnet property, go to Setup Controllers > Properties > Subnets...
1. Click on .
2. Rename the Subnet Name, if desired, to something that will make it easy to understand what is
included in that particular Subnet.
3. “Use In Find” allows a subnet to be viewed during autoconfiguration.
4. If there is to be a Proxy IP, enter the address. A Proxy IP is a software agent that performs a
function or operation on behalf of another application. For DoorsNXT, the Proxy IP is a software
service running on a computer attached to a remote subnet.
5. Enter the Gateway IP Address. The Gateway is the IP address of a router used to transport TCP/IP
data packets to network subnets that are outside of the local subnet.
