just used the Zyxel SFP module delivered by init7 4 years ago in it and it work great! My question: I have a Ubiquiti switch 10GB, NAS in 10Gb, Mac mini in 10GB.... how do I connect that to this router? Do I need to buy also a Ubiquiti SFP+ Modul UACC-CM-RJ45-MG? or can I redirect the SFP secondary to the Port 5 or 6 it does not seem to work hence my question... thanks a lot
