huklVodafone Germany 2025: Still no IPv6 if you run your modem/router/wifi box in Bridge Mode
8/8 Competence and Service. We're futuring over here! Put on your internet goggles and enjoy the ride on the data autobahn 😎
Ok nevermind. Vodafone v6 im Bridge Mode works but I had to configure it completely differently to what the intergoogles say. In Unifi I had to set it to SLAAC (single network) instead of Prefix Delegation on WAN and LAN.
Anyhoozle - finally got v6 at home which definitely didn't work in my previous - non-business contract.
simonhard@hukl I recently bought the ARRIS CM3500 B CE, which is a modem only and accepted/provisionable by vodafone kabel (west). Unifi WAN DHCPv6 + prefix delegation (/56). LAN SLAAC, which is imho fine. Works like a charm and finally no double ipv4-NAT anymore (FritzBox as the router).
@simonhard Yeah I might need a 3rd party modem as well because I've just realized that my Router/Modem isn't in Bridge Mode … although I've enabled it through the website but turns out they show my previous Vodafone Router/Modem there … *sigh
Do you know what the "B CE" stands for? Because I also see it in this shop without that suffix: https://netcon.store/arris/238/arris-cm3500-docsis-3.1-2.5g-port
@hukl I think, support for eurodocsis 3.1 (CE). But I don‘t know.
In the end the selection seems quite small for modem only solutions at vf.
Bought it here: https://www.werner-electronic.de/kabelmodem-arris-cm3500-b-ce-25-gbps-lan-port
The shop seems to address stuff to people like us :)
They also mention the predecessors of the ARRIS modem which are generally available at eBay etc
@hukl get ready for 30 minutes of question marks at the vf activation hotline and a consulted 3rd level tech, who confirmed the device is ok and provisionable. After 2h of waiting it worked…
