office365 ip addresses or fqdn

[ohareka70]

Hello,

I need to trial office365 from my corporate network to the Microsoft cloud going out via a Cisco 5580 firewall.

Can I use FQDN instead of IP, i.e. home.office.com, portal.office.com etc instead of IP addresses.

Is this a good approach?  or is their an easier way
 

any advice is welcome, Kevin

You can create an object that references an FQDN, and then use that in an access-list.

object network office.com
  fqdn office.com

access-list inside_in permit tcp any object office.com eq https

Hello,

I did this but i dont get any hits on the ACL.  I have just bought Cisco Firepower - maybe i can use that instead?
