Niagara R2 LON and Serial Tunnel Client Port Configuration

[Product_Support]

Issue

What port is used for the Niagara R2 LON and Serial tunnel clients?

Product Line

TAC IA Series

Environment

Niagara R2

Cause

Network configuration changes require port forwarding for tunneling. The correct port must be identified to allow communication through routers and firewalls.

Resolution

The LON and Serial tunnel clients use the same port as the UNC station.

• Default port: 80
• If the station port is modified, the tunnel clients will use the updated port number.
