Hello, I happily requested a new tunnel and subnet when I noticed that my IPv4 provider started two PoPs in my city. Unfortunately, for some reason, none of the IPv6 DNS servers seem to respond to the subnet I am using now ($subject). I tried different addresses, but no luck: root@lunchbox:/home/goodman# dig @nscache.eu.sixxs.net AAAA www.google.com ; <<>> DiG 9.7.3 <<>> @nscache.eu.sixxs.net AAAA www.google.com ; (6 servers found) ;; global options: +cmd ;; connection timed out; no servers could be reached root@lunchbox:/home/goodman# dig @2001:1418:10:2::2 AAAA www.google.com ; <<>> DiG 9.7.3 <<>> @2001:1418:10:2::2 AAAA www.google.com ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached etc... If I query www.google.com AAAA to the address in this round-robin from the tunnel provided by Amis Slovenia, I get a response: goodman@RLBSRV01:/root$ dig @2001:1418:10:2::2 AAAA www.google.com ; <<>> DiG 9.5.1-P3 <<>> @2001:1418:10:2::2 AAAA www.google.com ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32222 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.google.com.

I am not firewalling any dns traffic. Also, I can ping the DNS server in question from the "lunchbox" host so I think this can be an "allow-query" issue? Best regards, Daniel
