Using Glasswire to monitor all gateway traffic

If I connect Glasswire to a monitoring (mirroring) port between my ISP’s router and my firewall in a campus environment will Glasswire record all of the egress and ingress traffic between the campus and the ISP? Or does it only sense traffic relative to the PC running Glasswire?

GlassWire is made to only monitor traffic to your PC right now but we’re looking at adding full network monitoring in the future. The main problem we’re having is that there are so many different routers/devices that it’s difficult to pick what technology we want to use, plus it would require a lot of changes to GlassWire itself.
