Hmmm this is awkward… I was just checking this evening the boxes and it seems there was already one so I didn’t have to ask for it. I had seen no mention to it in any of the figures and I didn’t even notice it was there until just now. So I used this splitter and it seems to be ok now. I also noticed that there’s a small paper that mentions a “green guide” for connecting one of the devices separately and “blue guide” for connecting them together, but I’ve looked through all the materials in the box and there’s no “blue guide”. Maybe it wasn’t included by mistake? Anyway, not that it matters now (it was simple enough once knowing to use the splitter).
BUT I have another question. I’m configuring the new router and I’m unable to find where to set the port forwarding. In https://www.upc.ch/dam/www-upc-cablecom-ch/Support/manuals/en/int/Manual%20Wlan%20Connect%20Box%20Modem_1115_EN.PDF there’s a section for it, supposedly under “Security”, but my Connect Box “Security” menu only shows “Firewall”, “MAC Filtering” and “IP and port filtering”.
Is there ANY way of forwarding ports with this router? If not I’d rather keep using the other one!
Thanks
edit: I just found this http://community.sunrise.ch/t5/Internet-with-modem/Connect-Box-Menu-options-missing/td-p/79070 (maybe I should’ve googled harder before asking) I’ll try to call and see if they can do that ipv6-ipv4 change. Sorry for the silly questions.
