4.7 Improper Subnet Mask
The Subnet Mask does not match the Network ID so that traffic designated for a gateway goes to the Local LAN or traffic
with a destination on a local LAN is routed to a Gateway. The Subnet Mask is configured in the Setup System >
Networking Properties page:
Figure 3: Setup System - Networking Properties
4.8 Router Not Routing Traffic
For communication to controllers on different networks or subnets, the Router/Gateway must have a route configured. If a
route is configured in the Router, then verify that other devices on the two networks can communicate using the Ping
utility. When using Autoconfig to configure controllers on different subnets, make sure the DoorsNXT Proxy service is
running on a computer installed on the remote subnet and the IP address of that computer is set in the DoorsNXT Subnet
property.
4.9 Computer Has Multiple TCP/IP Connections
If a computer has multiple Ethernet devices, DoorsNXT currently communicates through the primary device. For
example, if a computer is connected to a LAN / NXT with a wired Ethernet cable and has its wireless network device
enabled, the communication may route through the wireless network. Disable the wireless network adapter to resolve this.
4.10 Incomplete Autoconfig
An Autoconfig was performed and the controller was detected, however the IP Addresses were not yet assigned. Click on
the Assign IP Address button or restart the Autoconfig process. Verify that the IP Address was assigned by checking the
status in the IP Assigned column in the Autoconfig tab in Setup System.
