Hi there!
I recently found out that my ISP supports native IPv6 via PPP/PPPoE, so I thought, I'd just give it a try. My provider mentioned that they would use prefix delegation with /56 networks. Since the FreeBSD user-ppp support IPv6, I thought it would be an easy task to solve. But I guess I as wrong
The IPv6-handshake went well for ppp:
But my provider doesn't give me an IPv6-address, only an address local to the interface (inet6 fe80::214:6cff:fe2d:a83d%tun0 prefixlen 64 scopeid 0x8).
From what I understand, I need my gateway to issue a dhcp6-request on the tun0-interface to request my prefix. Then, this /56 needs to be announced by rtadvd to the local network.
I found a patch for isc-dhcp4.1-client to allow dhcp6-requests on my tun0-interface, and that doesn't look too bad:
So... the problem is from here on I'm totally clueless, because my tun0-interface doesn't get an IP. I can set it manually with [CMD="ifconfig"] tun0 inet6 alias 2001:a60:10ff:8300::1[/CMD] and then I can even ping ipv6-addresses on the internet, but certain things still remain unknown to me:
I hope I gave enough information and I didn't sound too clueless

- How to go on from here? I read that I have to put something like this in /etc/rtadvd.conf:
but how do I get an IP from there for my gateway? rtsol refuses to work on the router.Code:
em0:\ addrs#1:addr="2001:a60:10ff:8300::":prefixlen#56:tc=ether: - Do I have to advertise the whole /56 via rtadvd? I thought one uses a subnet for every connected network (currently LAN and WLAN), so I need at least 2 subnets
- Is there a batter way to to dhcp6 than to patch that isc-client? I'd rather use the one shipping with FreeBSD.
- How to get my other Machines (windows, OSX and FreeBSD) on the network to play with ipv6 as well?
- Is there a good place for information about this? I'm really surprised that prefix delegation is totally uncommon and I found close to no documentation for it.
I hope I gave enough information and I didn't sound too clueless
