I access my ESXi 5.1 only via vSphere Client (local LAN), is it safe to close all ports below in my test ESXI server?
Firewall - incoming connections:
DHCP Client 68(UDP)
Fault Tolerance 8100,8200,8300(TCP)
SSH Server 22(TCP)
CIM Client 5988(TCP)
SNMP Server 161(TCP)
CIM SLP 427(TCP)
vSphere Web Access 80(TCP)
CIM Secure Server 5989(TCP)
DNS Client 53(UDP)
I just don't want to get locked out.... want to confirm it will disrupt VMs...
In advance, thank you for your help...
