6. Enter the Subnet Mask IP Address. The Subnet Mask is a method of splitting IP networks into

subgroups. The “mask” separates the portions of the IP address significant to the network from the

bits that are significant to the subnet. The subnet mask has the same format that is used by IP

addresses. An IP address of 192.168.100.1 with a subnet mask of 255.255.255.0 will only be able

to communicate locally to other IP addresses in the range of 192.168.100.1-254. Communications

to IP addresses outside of that subnet will be routed to the gateway.

NOTE: Once a Subnet property is created, controllers located on that Subnet will be assigned the

app

priate subnet data after an autoconfig is performed.

8. To delet

e a Subnet, click on the row to be deleted and click , followed by .

NOTE: At this time it is possible to delete settings that are currently in use elsewhere in the software.

Doing this

will cause the

program to not function properly. It is recommended that instead of deleting

any settings, change the name to “UNUSED.” This will be changed

in subsequent versions to not allow

deletions of functions that are in use elsewhere in the software.

5.2 Firewall and Network Security

The DoorsNXT server and controllers use specific ports to communicate to each other. These ports must

be allowed access to pass through routers and firewalls in order to allow proper communication. This

includes the software-based firewall applications, such as Windows Firewall, installed on any computer

running DoorsNXT software or services (server, client, and proxy).

1. The designated default ports should be left as is, unless instructed to change them by technical

support.

2. If instructed to change the ports, be sure to click to save the new port number, or click

to clear it without saving.
