many droppped DNS-requests from outbound IP at start

delphi99
hi,

I'm using Astaro at home. The PC is only powered on when I'm home.

My outbound interface is connected via pppoe and register itself at dyndns.

There are over 3000 dropped dns-requests to all DNS-root-Servers with over 200 packets per destination host, but only in the first minutes after start. Source is the outbound IP.

OK, it's not so bad, but I'm wondering about.

Have anyone any idea? I've some filter rules like "allow dns from any to any", but I think it's a problem with DynDNS?

Tnx Frank.

    It's strange that Astaro would drop traffic it originated. With fwrule="60003" and id="2001" in those lines, Astaro purposely dropped traffic originating on its interface.

    I don't think it's DynDNS.  If this began only recently, then check your Intrusion Prevention log.  If it's been going on for awhile, check your DNS configuration against DNS Best Practices.   Also the DNS setup in 'Remote Access >> Advanced'.

    Please come back with the answer if you find one, or more questions!

    Cheers - bob
