I am using the fiber connection for over 2 years with internet box standard. Now, I am trying to setup a UniFi Security Gateway Pro external router replacing the internet box. I am using an SFP module (1310/1490) and using VLAN 10. DHCP works and I can get an IP and ping the gateway successfully. However, after this I cannot access anywhere. If I open a web browser, it directs me to a page saying, this connection has not been activated yet, and it asks me a 6 digits code number. To get the activation code, it says to get in touch with the telecom service provider providing the following connection identification number, an 12 digit hex number.
I called the hotline, and they basically said they do not support external routers (which I understand) and all the information is on swisscom (public or customer center) pages. The only thing I can find regarding to this matter is to use VLAN 10 which I already do. So this was not helpful. Any further hints ?
