Configuring ESXi Firewall

You have to configure the firewall and enable SNMP access from monitoring servers to the ESXi host. You can set a subnet or a single IP address of allowed devices in the network.

We run these three commands to allow access from the 192.168.101.0/24 network to monitor ESXi via SNMP:

esxcli network firewall ruleset set –ruleset-id snmp –allowed-all false

esxcli network firewall ruleset allowedip add –ruleset-id snmp –ip-address 192.168.101.0/24

esxcli network firewall ruleset set –ruleset-id snmp –enabled true

Enter the IP address or a network address according to your network configuration.

A less secure configuration is to enable access from any network device:

esxcli network firewall ruleset set –ruleset-id snmp –allowed-all true

esxcli network firewall ruleset set –ruleset-id snmp –enabled true

ESXi SNMP configuration is done. Now you can configure your monitoring software on a monitoring server.
