    dns problems

    Hi everyone,

    I have completed a dns server configuration.
    Now, the LAN pcs can correct resolving NameServer and Address,use 'ping' and 'nslookup' is ok. But i get problems at external, its cannot to resolving the nameserver, i have the internet ip and have registration with the ISP. I'm sure the firewall have released the domain ports.

    anyone can give me some opinion.

    Use your ISP to host your domain information for viewing from outside your firewall. Internal machines will probably be using NAT, so you dont want external lookups to succeed on those. The only extrernal IP address you want people to see is the static IP for your mail server and maybe your web server (and these may well have the same IP address).
