Use specific gateway for a wildcard domain

[polletto]

Hi all!

I'm using PFSense 2.4.5 with 2 Gateways; first one is used for all traffic, secondary one is used only for failover.

Now I would like to pass some services like MS Teams through the secondary gateway, leaving all normal traffic to the main gateway.

I already know how redirect some specific host/network to the secondary GW by using rules or static routes, but MS Teams is using some wildcard domains (like *.lync.com).

I have no clue what i can do to make it, have you any suggestion?

Thanks

Maybe try pfBlocker and use it to create an alias using Microsofts ASN numbers, then policy route all the traffic through the secondary gateway.
