    Hello I just change from cable to DSL, unfortunately my ISP send me a wrong modem/router, my server is down until the new equipment arrive. I was able to configure most of my services except I thing my DNS server is not broadcasting the new IP. I verify this having a third party company to hold the DNS for one of my pages and it is working but the other pages on my server are not working.

    I have a linksys router port 53 is fowworded to the proper network ip. The slave server was able to update from master server.

    My question, is it a way to verify if the DNS server is broadcasting to the root DNSs?

    The DNS server is on a Suse 10.2, was working fine on cable but now is not on DSL.


    Best regards

    Yes, the Linux box has a fix IP, the server is working I had to use a free DNS service and is working now, but I am no able to resolve with my DNS server. My DNS server is not broadcasting or resolving.

    Does your router forward port 53 TCP and UDP?

    Are the IP addresses of ns1 and ns2 correct?

    If so, can you post the zone file of onlineatlastravel.com?

    No, those are the IPs before I moved from cable to dsl conexion, I change the IPs on the proper zone on mu DNS, but the server is not able to broadcast(update) the new information.

    You must change the nameserver settings and glue records in the web interface of your domain registrar.

    Thx will try that, but I do have a concern, why I did not have to do that with my previous ISP?

    Probably they did that for you.
