Re: [opensuse] Re: dhcpv6-pd
I had exactly that problem:

ISP gives me a /56 but reserves the right to assign a new prefix without
previous notice.

Solution: I'm using a prefix from the nonroutable fc::/7 range, and i
use NAT.

Yes, I know, one shall not NAT IPv6, but what else can I do.

I meant running one's own ipv6 router is not mainstream, not whether PD
is used by the provider. I'm sure the latter is already mainstream.

Was busy trying with pfSense ;-).

Maybe the setup is not mainstream, but what's the point of getting a
/56 prefix when you can't use all of the subnets ?
At the moment I don't really need all the subnets, but how I'm going
to use ipv6 on my internal network when at any moment my addresses can
change ? Of course I could just use the network right behind the
dsl-modem/router but I prefer having a linux firewall between my
internal network and the wild wide web.

An extra problem is my dsl-modem/router. Its firewall is too limited.
Standard all inboud traffic is blocked which is OK. You can allow
traffic through for a host (all or individual ports). But you can only
specify the host-part of the ipv6-address. That means hosts on a
different subnet are not reachable. But that's not on topic here.
