Hi all

I'm currently experimenting to host DNS zones on dynamic IP addresses
and dynamic DNS.

But I'm encountering more difficulties than expected on "broadband
connections" in receiving UDP port 53 DNS query packets. In one case
they're filtered completely (TCP port 53 works, UDP port 53 is blacked
out), while on some there seems to be some adaptive filtering requiring
like 10 minutes to "open up".

Does this ring a bell? I would be thankful about any hint what could be
interfering, PM or here.


Thanks!

Best
Claudio Luck
