Hi all, I have a strange case with unbound ... I have defined a stub-zone to query to a secondary DNS server: stub-zone: name: "mydomain.org" stub-addr: 172.22.54.4 stub-zone: name: "54.22.172.in-addr.arpa." stub-addr: 172.22.54.4 ... but it doesn't works: any hostname or IP address is resolved. But if I use "forward": forward-zone: name: "mydomain.org" forward-addr: 172.22.54.4 forward-zone: name: "54.22.172.in-addr.arpa." forward-addr: 172.22.54.4 all works ok. Then, which is the real difference between stub and forward zones? According to unbound's man page, stub-zone is used for authority servers, which is my case. But forward zones are valid for not authority servers. On the other side: "unbound performs the recursive processing itself for stub zones." ¿¿¿??? How?? Why?? If I use a stub-zone, it is because I have an authority server with recursion for its SOA domain ... I don't understand ... What is the correct configuration? -- Greetings, C. L. Martinez
