Hi there,

our ISP has given us an IPv6 address, so its time to implement it in our business network.
But, we are running to some problems we can't fix (kinda IPv6 noobs stil Wink )

The setup:
ADSL 2+ with static IPv4 and a /48 IPv6 (IPv6 prefix: 2001:981:51b8::/48)
Fritzbox modem (2001:981:51b8::1 || ULA: fd00::2665:11ff:fea4:4bd5/64)
connected to that Fritzbox is a server running M0n0wall V1.34
- WAN DHCP (interface shows a IPv6 and IPv4 address that was given to it form the fritzbox)
- LAN Static 2001:981:51b8:10::1/64
Windows SBS 2008 server is running DCHP server in range 2001:981:51b8:10::1000 to 2001:981:51b8:10:0:ffff:ffff:ffff
PC's getting IPv6 somewere in the specified range, so that is ok.

What works:
M0n0wall gets a IPv6 and gateway from the Fritzbox on WAN
PC's get IPv6 address and DNS from sbs server

What doesn't work:
Can't ping the m0n0wall LAN IPv6 (ping -6 2001:981:51b8:10::1)(general fault) from PC
Can't ping the Fritzbox LAN IPv6 (ping -6 2001:981:51b8::1)(general fault) from PC
Can't ping the m0n0wall WAN IPv6 (ping -6 2001:981:51b8:1:20c:29ff:fe60:4971)(general fault) from the PC
Don't get a IPv6 gateway (no where to configure in sbs2008) on PC's
From the m0n0wall i can't ping (got 100% loss): ipv6.google.com, the Fritzbox gateway address, the Fritzbox LAN address
And of course, can't internet on IPv6. (except when I connect to the Fritzbox WiFi with my notebook, that I can, so the internet IPv6 does work)

What can i do to fix this?
If you need any more info, let me know, that I will get it for you.

Thanks in advance!

It's hard (for me anyway) to visualize your network topology and exactly how things are configured. A diagram with all machines fully numbered would be helpful.

The feeling I do get is that your prefix 2001:981:51b8::/48 is being used everywhere on everything on every interface. That's not how a routed subnet works.

I'd also say that the IPv6 implementation in m0n0wall 1.8 is further along than in 1.34

I'm no IPv6 expert, but I do have it working here on m0n0wall 1.8 and my LAN.
