ok well I now know the answer.
It was setting an Input filter when you have two subnets. a DNS server is on subnet#1 and clients on Subnet#2 what I failed to understand is what the existing session had to do with it.
I found out that the clients start a session then the DNS server respondes to that if the traffic from subnet#1 tried to send data to subnet#2 it would be blocked but because its responding to a session started but the clients on subnet#2 it is allowed to pass therefore the the DNS server can still resolve the query.
Now I know what I needed to know but I cant refer anyone to a site with the info as I couldn't find one.
