F5 DNS what specific TCP/UDP port need to open?

[T0nyP]

Hi F5 Community,

We are restricting thru Port Lockdown our F5 DNS system which is facing Internet.

Does UDP/53 and TCP/4353 already enough?

Or we still need to open both TCP/UDP 53 and TCP/UDP 4353?

Thanks,

Tony

Hi

So i think if you would like to enable about security DNS or zone transfer, You have to open TCP 53 and TCP 4353 for protocol IQUERY

Thanks you
