One LAN subnet - Block Internet, Allow Office 365
I currently have an access rule to DENY from LAN to WAN a couple subnets. I now need to give one of these subnets access to Office 365 (exchange online specifically). I see there is an app control for 365. This can't be globally on the LAN as we have multiple subnets. Googling around, it seems content filtering seems like it would work, but how can I apply to just one subnet?
Is there an easy way to accomplish this?
