Hello Experts,

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)
vMotion  8000(TCP)
NFC  902(TCP)
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)
DHCPv6  546(TCP,UDP)
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...

If you are not using the ports, they can be closed.

They will not affect VMs, these ports are Open Ports, on the Management Interface of ESXi.

these are points normally required in this VMware KB
