I'm attempting to manage ESX 4.0 hosts that sit in front of the firewall that protects my vCenter 4.0 Server. The ESX hosts are public. After a minute or two the hosts drop out of the cluster and say "Not Responding". I've set the firewall to time out 'never' on the ports that I've assigned to it. The firewall is a Juniper SSG-550. I've got these ports opened:
53, 80, 389, 427, 443, 626, 902, 903, 905, 5988, 5989, 8080, 8443, 9000-9010, and 27000-27010
Can anyone offer a solution to why my hosts drop out of my cluster? If I put them on the private network behind the firewall they stay with no issue. I can't open console on the VMs then from a public connection.
