Firewall Requirements | Nutanix Community

Firewall Requirements | Nutanix Community

Use these firewall requirements to configure rules in your external firewall to allow Nutanix Remote Support, Pulse, SMTP, 1-click upgrades, and LCM updates.

Source	Controller VM / Prism Central IP addresses
Destination	nsc01.nutanix.net and nsc02.nutanix.net
Protocol - Port	TCP - 80 and 8443
Action	ALLOW

Source	Controller VM / Prism Central IP addresses	Allows Pulse messages from the cluster to Nutanix support servers. Each Controller VM in your cluster collects Pulse configuration data continuously and sends Pulse metric data every 15 minutes to insights.nutanix.com over port 443 once every 15 minutes over HTTPS. Ports 80 and 8443 are the default ports that the cluster uses to connect to the Nutanix support servers nsc01.nutanix.net and nsc02.nutanix.net. Nutanix recommends that you open both ports. If one port is disabled, the cluster automatically tries to connect on the other. You can open the ports directly or make them available through an HTTP proxy. Pulse messages are not HTTP formatted, so if you use a firewall that only allows HTTP traffic through port 80, Pulse requires access through port 8443. Pulse uses the SSH protocol for communication through the firewall. Firewall port requirements are automatically met if you have a Prism Central deployment, see "Prism Central Proxy for Pulse Data" in the Prism Central Guide.
Destination	insights.nutanix.com
Protocol - Port	For insights.nutanix.com: TCP - 443 For nsc01.nutanix.net and nsc02.nutanix.net: TCP - 80 TCP - 8443

Source	Controller VM / Prism Central IP addresses
Destination	insights.nutanix.com and designated email addresses (if any)
Protocol - Port	TCP - 443
Action	ALLOW

Source	Primary Site Controller VM IP addresses (including Virtual IP Addresses)
Destination	Replication Site Controller VM IP addresses (including Virtual IP Addresses)
Protocol - Port	TCP ports 2009/2020 - AOS communications UDP port 53 - DNS HTTPS port 443 - AWS or Azure communication TCP port 22 - SSH communication to Nutanix Controller VM TCP port 3000
Action	ALLOW

Source	SMTP Server IP Address	Allows cluster e-mails to be sent to Nutanix Support for Pulse. If your security policy does not allow ports 80 and 8443 to be opened, Pulse can send messages using any accessible SMTP server. If you do not have an SMTP server, you can use an HTTP proxy.
