Contributors netapp-bcammett

Cloud Manager creates Azure security groups that include the inbound and outbound rules that Cloud Manager and Cloud Volumes ONTAP need to operate successfully. You might want to refer to the ports for testing purposes or if you prefer your to use own security groups.

Rules for Cloud Manager

The security group for Cloud Manager requires both inbound and outbound rules.

Inbound rules for Cloud Manager

The source for inbound rules in the predefined security group is 0.0.0.0/0.

Port Protocol Purpose

22

SSH

Provides SSH access to the Cloud Manager host

80

HTTP

Provides HTTP access from client web browsers to the Cloud Manager web console

443

HTTPS

Provides HTTPS access from client web browsers to the Cloud Manager web console

Outbound rules for Cloud Manager

The predefined security group for Cloud Manager opens all outbound traffic. If that is acceptable, follow the basic outbound rules. If you need more rigid rules, use the advanced outbound rules.

Basic outbound rules

The predefined security group for Cloud Manager includes the following outbound rules.

Port Protocol Purpose

All

All TCP

All outbound traffic

All

All UDP

All outbound traffic

Advanced outbound rules

If you need rigid rules for outbound traffic, you can use the following information to open only those ports that are required for outbound communication by Cloud Manager.

Note The source IP address is the Cloud Manager host.

Inbound rules for HA systems

The rules listed below allow traffic, unless the description notes that it blocks specific inbound traffic.

Note HA systems have less inbound rules than single node systems because inbound data traffic goes through the Azure Standard Load Balancer. Because of this, traffic from the Load Balancer should be open, as shown in the "AllowAzureLoadBalancerInBound" rule.
