Network Services

The Control Center is designed to receive and respond to requests from Local Managers. In secure environments, exceptions made need to be made in firewalls to ensure proper operation.

Ports Used

The following inbound ports are used during normal operation.

Port	Protocol	Function	Description
443	TCP	HTTP	provides access to the Control Center GUI - required
8443	TCP	Heartbeat and Archive	used for communication between Control Center and Local Managers - required
7	TCP	Echo	used by the Pulse feature
22	TCP	SSH	used to connect to the Control Center CLI
2222	TCP	Reverse SSH	used by Local Managers to create a reverse-ssh tunnel with the Control Center
2244	TCP	Reverse SSH	used by clients to connect to Local Managers via the reverse-SSH tunnel
80	TCP	HTTP	provides access to the Control Center GUI, redirects to 443
123	UDP	NTP	provides NTP servers to managed devices

If you will be using the SOCKS proxy server, you will also need to open TCP 1080 (typical default) or TCP 9000 (as suggested in our documentation).

Note

This information is for use with external firewalls and NATs. The Lantronix Control Center runs its own firewall to ensure only the above ports are accessible.

Traffic Compression

The use of network traffic compression services / devices is not recommended for Lantronix products. Devices such as Riverbed accelerators / optimizers may cause Heartbeat and Pulse features to fail.

Lantronix recommends adding exceptions for the ports listed above to ensure proper operation.
