And for French guys who try to get the manual, it seems that the French version of cablecom website is missing the new Connect Box page. So just change to German or English to access the Connect Box manual.

Thank you so much for your solution.
I just called the hotline for asking about the port forwarding menu that is missing. The guy told me that the only solution is to set up my router as a bridge and use another router…(please cablecom, next time you hire a tech guy, hire a REAL tech guy…) So I was looking on Internet about the modem/router CH7465LG but didn’t found any relevant information except the official manual that shows me many more menus that the interface currently have (but nothing about ipv4 vs ipv6 difference). By chance I came on this thread and now I can phone the hotline with a more precise question “Can you change my Connect Box from ipv6 to ipv4 please” instead of “Port forwarding menu is missing, what can I do to have it?” hoping the tech guy will understand this time…
