ipv6 not "Labor only" or beta anymore

Fritzboxes 7390, 7320, 7270(v2, v3), 7240, 6360 Cable, 3270 and may be more
support IPv6 in recent released firmware

Yes, we are aware of that. It will be included in the next iteration of the matrix. But more importantly we are curious about experiences with this new code, especially on the cable side of things.

Here's some IPv6 issues I've found with the AVM code for the 7390 -

o IPv6 full rate throughput half IPv4's at 100Mbps in the upstream
direction over an EWAN / PPPoE service.

o Curr Hop Count in RAs set to 255, not 64 or zero

o MTU of 1460 announced in RAs, not PPPoE MTU, or left as LAN default so PMTU takes care of PPPoE "dumbbell MTU". This will reduce intra-LAN throughtput.

o IPv6 firewall doesn't permit any other inbound protocols other than
TCP / UDP. At a minimum, other transport layer protocols such as SCTP or DCCP should be possible to allow through the firewall by specifying their transport layer protocol number, predefined names for them would be better. An option to permit all transport layer protocols should also be provided if the user wants to have all their IPv6 firewalling performed by their host's IPv6 firewall.

o ULAs don't include a 41 bit random number, it is set to all zeros.

getting ipv6 into avm's firmware is all very well. but their ipv4 implementation is badly, badly broken because it wrongly assumes everything gets NAT'ed behind one public IPv4 address and inbound port forwarding can only go to one box on the LAN: ie incoming SSH (say) can only get forwarded to one internal host. i have no idea why they can't/won't fix this.

avm's customer support is remarkably clueless too. they think everyone runs windows, even when you tell them you don't.
