Attendance on Demand Service End Points for Connectivity – CTR/NY Help Center

IP Addresses

If you or your clients restricts external web access by adding allowed IP filters to a firewall or connecting software, ensure these Attendance on Demand IP address ranges for HTTP, HTTPS, and SMTP ports are included in the list of allowed IPs.

205. 145. 130. 160/29
205. 145. 131. 96/27
205. 251. 181. 128/25
207. 75. 127. 0/24
216. 234. 123. 80/29
152. 160. 49. 0/24

Outbound Ports to allow:
HTTP Port (TCP 80)	SMTP Port (TCP 25)
HTTPS Port (TCP 443)	Web Services Port (TCP 8192)

*Access to port 8192 must be allowed in order to connect to the web services API.

Here are the ports that need to be open for the GT Line of Time Clocks.

When implementing GT series clocks using GT Connect the client will need to ensure that the following hosts and IP addresses are configured for two way communication.

register.gtconnectedservices.com, TCP port 443 (HTTPS)
global.azure-devices-provisioning.net, TCP port 5671 (AMQPS)
iot-hub-aegis-eastus2.azure-devices.net TCP port 5671 (AMQPS)
device.gtconnectedservices.com, TCP port 443 (HTTPS) - (Application Communications)
remote.eastus2.gtconnectedservices.com, TCP port 443 (HTTPS) - (Interactive View)

To minimize disruption, use the hostnames for networking and firewall configuration whenever possible. Clocks are set to DHCP.

Device needs to be rebooted after firewall changes

If you have any questions about how to do this, please contact your IT-Staff or Network Admin.
