Ahh I see, so my access is based on registration to one router (MAC address in this case). That would make sense as to why I can't get past the gateway. Thanks for sharing that info, I like the idea of spoofing too. Anyway, i'm waiting for my Fiber7 connection to replace Swisccom, another week i think, so i won't have to deal with this much longer.
How can I spoof the MAC address of my SFP port on EdgeOS in this case? Command?
Again great guide, maybe this something you can put in your notes for the Swisscom section. I have some friends that are interested in doing this same setup so i'll share this guide to them!
