    Try to use the free google dns servers in /etc/resolv.conf to see if that fixes the problem. The IP addresses are:

    8.8.8.8
    8.8.4.4

    You can configure your router to use Google's nameservers (or any other nameservers).

    not option for use external nameservers

    First thankyou for your time mates :)
    we can't use externals servers, if do it, then the servers not works with wordpress (for updating or similar, can't operate bicause calls points to router ip, with the subsequent resolution name process result broken

    this is the problem:
    from local network with our NS
    ping to our.domain.net resolves ok 192.x.x.x
    ping to another.external.net resolve - some OK & some fails
    be
    from internet: resolves OK and NAt works fine.
    --- this is the configuration it worked before -----


    from locale with externals NS:
    ping to our domains resolves to our.router.ip then not mach

    that is
