Office 365 traffic

We have a connection to the Internet and now we just added another Internet connection. We want to use the new Internet connection just for Office 365. I am not sure how to go about doing this as I have a default route from my core to the FW and then from the FW to the provider router. So currently all Internet connection, including O365, is pointed to the default route and there is nothing going out of the the new Internet connection.
We have a physical connection from the provider to the FW, then from the FW to the core switch.

Any thoughts? Thanks

Hi Leblanc,

You can achieve this with PBR (Policy-Based Routes) in your Firewall. What is the make/model of your Firewall?

Since Office 365 uses many common ports (25, 80, 443, etc.) you will have to create the PBRs by identifying the Destination addresses of the Office 365 hosts. You can find them all here: https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2 Assign a low metric to raise priority of the PBR.

Since you have dual WAN connections I'd recommend setting up a WAN Failover policy so that when WAN2 (Secondary WAN) goes down everything from O365 will route dynamically via PEPBR (Probe-Enabled Policy Based Routing) to WAN1 (Primary WAN) and then when WAN2 comes back online all O365 traffic will route back through WAN2.

Let me know if you have any other questions!

You may want to look into Azure ExpressRoute


Routing with ExpressRoute for Office 365
Office 365 requires Microsoft peering.

Do you have any questions with what I proposed?

Also, routing with ExpressRoute for Office 365 will not achieve what Leblanc is asking because ExpressRoute circuits aren’t mapped to specific physical infrastructure, but are a logical connection made at a single peering location by Microsoft and a peering provider on your behalf.
