Yes thank you I eventually got it to work. I cloned my swisscom modem MAC and that have me a public IP. For those stuck I would suggest to activate the connection with your swisscom box and then clone the MAC on your own router. And don't forget to configure a dns server. I had forgotten and of room me quite a while to realize...
I switched to using my own router with my Swisscom FTTH connection. I am using an MC220L with Swisscom's SFP module and my own router (OpnSense) When I try and access the internet, I am getting the following page: I called customer service but they didn't know what I meant because the connection is activated and works with the Swisscom modem. How do I get my 6 digits activation code?
