Hope your all well,
I am currently looking at not only implementing a new DMZ but also allowing for our migration to Office365 services with that. I was hoping to reach out and ask how people have faired with O365, already I am hitting bumps in the road relating to Office 365 URLs/IPs that really look like they need FQDN config, unless I want to spend all my time constantly updating firewall rules.
Has any one been able to get around this hurdle on their Cisco ASA Firewalls? I am thinking that perhaps there is something I can do policy wise in the firepower module, however I believe that this will need URL filtering license.
Any advice would be welcome in regards to your success/failure's
Thanks for your time!!
