Hi,

EDNS is enabled by default. It can be disabled in a per server basis. That means that you can disable it for a server that you have edns problems with.
nmap shows that port 53 tcp is filtered, meaning that it could be a firewall blocking that port.

Regards

Hi people;

You may notice that I have edited many posts in this thread to remove what I deemed to be personal information, including IP addresses, domainnames, and email addresses, which were initially posted by the OP but which he has requested be removed from the thread. I have tried to do this in such a way as to not make the thread incoherent, but there was a lot of it, so no guarantees; I tried though.

@ saurab -- Please verify that all personal information has been suitably removed from the thread. In the future, please be more careful, and appropriately mask out or alter your personal info before posting

If I have missed anything, kindly report the post(s) again, and I will fix it.

Cheers,
Sasha
