    Hi guys,

    Recently I changed my internet provider and had to move to a VDSL connection and I started having dns issues.
    My network is like this now:
    VDSL ModemRouter from internet provider which has the external ip, lets say,
    90.91.92.93. The router has NAT on 192.168.1.0 – 255.
    Then I have my internal router that has the ip 192.168.1.2 and which also has NAT on network 10.0.1.0 – 255.
    The DNS and mail server is on 10.0.1.200.
    I routed the ports for DNS, mail, etc on both routers to point to 10.0.1.200.
    The forward lookup zone works ok, i have defined the mx record on mail.mydomain.com and also on domain.com and have A records for mail, www, ns, ns1, ns2 with the external ip, 90.91.92.93. The FQDN record has all the ips: 90.91.92.93, 192.168.1.2 and 10.0.1.200.
    The reverse dns lookup zone is defined on the external ip and is like 92.91.90 – …. Ihave defined a PTR record for mail.mydomain.com with the external IP but it still when I check from the exterior it doesn’t recognize the reverse lookup.
    Can you please help?
