Ok, let me renumber (and reword).
I must be wrong with the English words i use. I doubt our company is
registered as the address range owner (i think (legally) using some
addresses would be more accurate than having).
My ISP have some address space (don't know how large actually).
I have the address space 2001:db8:100::/56 (mask is true)
My ISP gave me the extra (single) address 2001:db8:0:ffff::2 (lower than
my address space) from their address space, and using 2001:db8:0:ffff::1
as gateway. This subnet is only /112 large (they gave me this netmask -
should i use the word "address range" instead of subnet?).

RFCs are quite optional in Hungary... 60% of our dear ISPs are don't
even know they are making PathMTU undiscoverable and even what is it for...
You need to use policy routing tables to fix that up, or...
Ok, i'll start reading
http://www.policyrouting.org/PolicyRoutingBook/ONLINE/CH09.web.html
Install OpenNTPd instead of the IMHO broken(*) ISC ntpd, in openntpd you
can specify "listen on 2001:db8::1" and "listen on 192.0.2.1" to specify
exactly which IP addresses to listen on. Problem solved.
Ok, then it was not only me who tought ISC ntpd is broken, i always
tought i do something terrible...
Thank you, i'll try it out.
Same for software like Postfix etc. Not nice that you have to do it per
app, but that is the way it is.
Well actually postfix sits on a domU, so it has only a single global
ipv6 address. Same with most of the services. Actually i had problem
with ntpd only...
