Hello all,
Can anyone tell me if there is a good reason to allow connections to
a local DNS port(53) from remote privledges ports(< 1024)?
As I understand it *all* DNS is one of:
local port remote port
(53) <-> (53)
(1024:65535) -> (53)
(53) <- (1024:65535)
and there should never be:
local remote
(53) <- (1:1023)
(1:1023) -> (53)
