So you're absolutely sure the hardware environment is fine. There are two important tactics to employ then in troubleshooting. First one is to bypass every equipment and connect the troubleshooting device direct to the upstream connection. Then ensure you have full connectivity and move down the line to the point you find your issue. You would follow this with the second tactic, drop the configuration from zero and make sure you have working connectivity and then start adding each piece of the software set up, until you find the part that generates the issues. > it is pure a dns isue, but what i can resolv, i rewrote the complete > named stuff, added even the DNS server pool from that website, heck, > still no result... Try unbound / nsd and see if this gives you a different result. It is often just such a simple common issue, that it's hidden in plain sight. Once you have found it, please report to the list your process+results.
