Hello, Should we change the "Listen on " in the file named.con.options. By default that indicates whether the loopback address 127.0.0.1. I amend it to show my public IP address. Example: options { directory "/var/cache/bind"; // If there is a firewall between you and nameservers you want // to talk to, you may need to fix the firewall to allow multiple // ports to talk. See http://www.kb.cert.org/vuls/id/800113 // If your ISP provided one or more IP addresses for stable // nameservers, you probably want to use them as forwarders. // Uncomment the following block, and insert the addresses replacing // the all-0's placeholder. // forwarders { // 0.0.0.0; // }; auth-nxdomain no; # conform to RFC1035 listen-on { 127.0.0.1;}; listen-on { 88.xxx.xx.xxx;}; }; Thank you Sincerely,
