vRA 7.2/7.3 SQL and IAAS servers Firewall

Hi,

I have the below question in vRA 7.2/7.3 installation,

1) I am installing external SQL server, Is it windows firewall needs to enable on that. If enabled what are the configurations I need to do in Windows Firewall to communicate vRA and IAAS.

2) Is that windows firewall needs to enable in IAAS, if yes what are the configurations I need to do in Windows Firewall to communicate vRA and SQL.

3) If I installed multiple iaas server, Do I need to follow the same configuration to all IAAS servers ?

Thanks,

Srini
