Configuring network firewalls correctly is essential for the smooth distribution of Golden Software concurrent licenses across your organization. Surfer and Grapher rely on Sentinel RMS License Manager, which communicates strictly via UDP port 5093 between client workstations and the central license server. Use this guide to verify port requirements, understand automatic rule creation, and manually configure Windows Defender Firewall rules for seamless license allocation.

Key Firewall Specifications:
- Protocol & Port: UDP Port 5093 (TCP port 5093 is not used).
- Direction: Must be opened for both Inbound and Outbound traffic.
- Scope: Must be configured on both the license server machine and all end-user client PCs.
Automatic Port Opening
During the installation of the Sentinel RMS License Manager on your server, UDP port 5093 is typically opened automatically in Windows Firewall unless explicitly denied by corporate group policies. If the installation completes successfully and client PCs are able to connect to the license server, no further action is necessary.
During the installation of the Sentinel RMS License Manager on your server, UDP port 5093 is typically opened automatically in Windows Firewall unless restricted by corporate group policy. If installation completes without security warnings and client PCs can connect to the server, no further firewall configuration is required.
Manual Windows Firewall Configuration Procedure
In cases where UDP port 5093 is not opened automatically, for example if your corporate security policies prevent automatic rule creation, follow the steps below to manually configure the Inbound and Outbound Rules in Windows Defender Firewall on both the license server and client machines.
Steps to Open UDP Port 5093
- Navigate to the Control Panel on your computer
- Go to System & Security > Windows Firewall > Advanced Settings
- Here, you will create two new rules: an Inbound Rule and an Outbound Rule
Creating an Inbound Rule
- Click on 'Inbound Rules' on the left sidebar, and then ‘New Rule’ on the right sidebar
- Select 'Port' and click ‘Next’
- Choose 'UDP' and specify the local port as 5093
- Select ‘Allow the connection’ and click ‘Next’
- Ensure the rule is applied to Domain, Private, and Public by checking all options and click ‘Next’
- Name the rule (e.g.,
Golden Software License Server - UDP 5093 Inbound) and click Finish.
Creating an Outbound Rule
- Click on 'Outbound Rules' on the left sidebar, and then ‘New Rule’ on the right sidebar
- Repeat steps 2 through 6 above, selecting Allow the connection and naming the rule appropriately (e.g.,
Golden Software License Server - UDP 5093 Outbound).
Confirmation
The opening of UDP port 5093 is typically confirmed when any Golden Software product is installed and runs successfully with a concurrent license on the client machine.
Ensuring that UDP port 5093 is open on both the license server and client computers is crucial for the uninterrupted and efficient distribution of Surfer, Grapher, or Strater concurrent licenses. Follow the outlined steps to manually configure the port if it isn’t automatically opened during the installation process.
