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).
Thomas Ott@simonhard @hukl this sounds really interesting fo me. I’m currently running Vodafone with my TC4400. IPv4 and IPv6 work, but I’m having problems with prefix delegation because I only get a /64. Right now, I have no idea how to obtain a /56 from Vodafone. Do you think this is a Vodafone issue or a firmware problem with the TC4400?
@greenchapter I think it‘s a backbone issue. The modem is imho on layer 1 & 2.
Or the TC4400 does the PD by itself and forwards only /64. but I can‘t imagine that.
I‘m at vf west (unitymedia). Maybe you‘re not.
