Hello,
I wanted to ask what the current status is with NAT64 /DNS64. Over a year ago I asked if this function would be integrated and was told it was coming but not when. Is there anything new on this topic?
Hello,
There are no plans to implement DNS64 at the moment, but NAT64 should be included in future firmware releases. It will most likely be available in a few months. I will let you know once it has been released.

Hello,
I would like to inform you that with the release of RutOS firmware version 7.10, NAT64 is now supported! However, please note that it is currently only available via SSH.
Best regards,
Many thanks for the info,
I had read the changelog, but did not find any jool on the router. I also tried to compile it but it did not work. Is there a manual ?
Best regards
Hello,
Could you please specify which device and model you are using?
Best regards,
Im use the Rut241, RutX50, RutC50 and TRB500.
Hello,
Could you please share more details about your use case for requiring both NAT64 and DNS64? Thank you!
Best regards,

A client on the LAN sends a request in ipv4, for example www.google.de (172.217.16.163). The router should then convert it with the prefix 64:ff9b::172:217:16:163 so that it can pass through the WAN. I would do the DNS query via Google DNS64. Jool would do the conversion mentioned above. I hope I have explained this clearly.
Hi,
Your explanation is clear.
In your case you need not NAT64, but 464XLAT, specifically CLAT(Customer-side translator) support.
Jool package is made up from two parts, jool and jool_siit. With RUTOS 7.10 only jool part responsible for NAT64 was added so IPv4 clients in LAN could be reachable from IPv6 networks in WAN but not jool_siit part which does IPv4 → IPv6 translation.
RUTX50, RUTC50, and TRB500 devices devices have modems that should support CLAT functionality natively. Could you change the PDP type for the mobile interface to ipv4v6 and check if 192.0.0.x IP address is received on the mobile interface? If this address is received, then IPv4 destinations should be reachable.
If mobile interface won’t receive IPv4 address, could you provide output of gsmctl -A 'AT+QCFG="CLAT"' command?

Hello,
the TRB500 Response :
+QCFG: “clat”,1,1,“”,0,“ipv4only.arpa.”,0,0,1,1,1,1
Output seems to be good, did your mobile interface receive 192.0.0.x IP address after setting PDP type ipv4/ipv6 in Network -> WAN -> Mob1s1a1?
The device recived the ip Adresse correct.
So if 192.0.0.x ip is received by your mobile interface then you can assume that modem is performing ipv4 → ipv6 translation, your end devices should be able to reach internet via IPv4.
