I have a web / dns server. I configured IP Filtering with the following :

TCP
25
21
80
443
53

UDP
53

But the DNS query isn't working. I am wondering if the DNS server is forwarding the request on say port 1003 to our ISP DNS port 53 (which would work with the rules above). But the remote DNS server is sending back to 1003 which isn't listed. Anyone get this to work ?
