How to change StarWind Virtual SAN default port value

Introduction

This article explains how to change the default port used by StarWind Virtual SAN for iSCSI communication. By default, StarWind operates on ports 3260 and 3261, which may conflict with third-party applications that use the same port. The guide provides a step-by-step process for modifying the port value in the StarWind configuration file and applying the changes by restarting the service.

Solution

1. Open StarWind installation folder. Default path is  C:\Program Files\StarWind Software\StarWind
2. Search for StarWind.cfg file and open it (preferably using WordPad opened with administrator rights).
3. Find “<Port value=”3260″/>” and change Port value attribute to another one. Note that variable <Port value> is integer.
4. After the change is done, restart StarWind service in order to apply the change.

The other workaround is to change port settings on the 3d party application or uninstall it.

Most common use case

In the major part of the situations MS iSCSI Target Server reserves 3260 port. Thus to eliminate any possible conflicts, change StarWind Virtual SAN default port to any other free custom port.

Conclusion

Changing the default StarWind VSAN port is a simple yet effective way to resolve conflicts with other applications that use standard iSCSI ports. By updating the configuration file and selecting an available port, administrators can restore proper data transfer functionality. This adjustment ensures uninterrupted storage operations and helps maintain stable connectivity within the virtualized environment.
