Hi All,
Just got a request to route Skype traffic differently when a user is connected to VPN vs not connected. In Windows, this firewall rule is super easy, but I can't seem to figure it out on the Mac.

Does anyone know if this is even possible with the built-in Firewall?

Thanks!
Matt

I don't believe you'll be able to do that using Application Layer Firewall. Separating traffic per interface can be accomplished using the PF firewall. You can create rules in pf.anchor and call them from pf.conf.

Here's a good read [https://pleiades.ucsc.edu/hyades/PF_on_Mac_OS_X](link URL)
