<p dir="auto">I have a VLAN network for unprotected machines (no AV, no updates, etc), where all connections to internet are not allowed, only between networks who are behind our firewall.</p>
<p dir="auto">Till now, I was using rules on firewall (a pfsense), to allow destinations for an alias with a list of hosts, where in that list, are FQDN.</p>
<p dir="auto">Now I was trying to let that network access office365 OWA (https://outlook.office.com ), but doing that way, it gave me an error launched by office365:</p>

<p dir="auto">How would you setup a rule in your firewalls to perform this?</p>
