Hello Jordi,
thank you, I will take a look on Jool!
Exactly CLAT was the issue.
First, I thought to provide a /128 to every mobile, and then do a static
6to4 to certain public IPv4. But it seems mobile need a /64, and it uses
a lot of random IPv6 inside assigned /64, several addresses together at
each time, CLAT uses the most of it (on Android). So direct translation
6->public4 is impossible.

Do you really mean 6to4 or NAT64? Totally different things ...
If that's the case, I will suggest you go for Jool instead of Tayga.
Also, if you want the customers are able to use old IPv4 apps and devices,
NAT64 is not sufficient, you need also CLAT at the customer premises (so they
can run 464XLAT).
Regards,
Jordi

Asunto: IPv6 and forensic requests
Hi All,
we are implementing IPv6 only infrastructure.
For IPv4 access, we using tayga for 6to4 translation and then CGN for NAT.
There is a number of ways for Linux based NAT to store information for
future forensic requests (i.e. "who was it cracking that website?").
But what about 6to4 translators, as tayga? I believe there should be
well-known patches or solutions. The aim is to have what /64 (not even
/128) was translated to what IPv4 at the requested time.
Is there any?
