To resolve the issue:

  1. On the Deep Security console, go to Policies > IP Lists.
  2. Create a new IP list for the related cluster IPs.
  3. Go to Policies > Port Lists.
  4. Create a new port list and enter 3343 and 49152-65535. Make sure to put one port or port range per line.
  5. Create a customized firewall rule that allows incoming TCP/UDP port listed on 3343 and 49152-65535.
  6. Apply the newly customized firewall rule to the target cluster IP list.
