Testing Network Port Connectivity for NLO Servers

Use this procedure to verify whether a client computer can communicate with the GibbsCAM Network License Option (NLO) server across the required network ports.

Default Port Numbers

• Reprise NLO Server: 2764 and 2765

Step-by-Step Port Test Procedure

1. Open Windows PowerShell on the client computer via the Start menu.

2. Run the following command: PowerShell

   Test-NetConnection IPAddress -Port XXXXX
   

   Replace IPAddress with your NLO server’s IP address and XXXXX with the target port number (e.g., 10106).

3. Repeat the steps to test both ports
   

4. Review the test results:
   

   • TcpTestSucceeded : True — The client can successfully connect to the server over the specified port.

   • TcpTestSucceeded : False — Communication is blocked between the client and server.

Troubleshooting Failed Connections

If the connection test fails (TcpTestSucceeded : False), the network traffic is being interrupted before reaching the licensing service. Common causes include:

• Windows Firewall: Ensure inbound rules exist on the server to allow traffic through the specified port.

• Security Software: Antivirus or third-party endpoint security software may be blocking network calls.

• Network / Router Policies: Subnet routing, corporate hardware firewalls, or VPN policies may prevent access.

Work with your network or IT administrator to permit traffic over the required ports.
