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
