Resolving connectivity issues in Microsoft Cluster Environments when using a Deep Security Agent (DSA)

Summary

Customer installing a DSA might encounter connectivity issues in Microsoft Cluster Environments.

This can either affect a Microsoft Failover File Cluster or a Microsoft SQL Cluster.

Details

To resolve the issue:

Create a customize firewall rule allowing incoming TCP/UDP port listed on 3343 and 49152-65535.
Assign the custom firewall rule to the target DSA. The said ports are required for MS Cluster Service to allow multi-node communication between the MS Cluster Management Server and cluster nodes.
You may change the Source IP value to Incoming Traffic instead of Any.

The nodes should now be working normally. For more information, refer to this Microsoft article: Service overview and network port requirements for Windows.
