Filter coming in, out, or out AND in?

For going out, the port starts at 1023+, so that could be your problem. The
destination is 53.

Subject: [NTISP] IP Port filtering in NT

I am setting up a new server and want to lock it down.

I set port security to block all ports except those listed below. Now DNS
lookups no longer works

25 TCP
53 TCP/udp
80 TCP
110 TCP
123 TCP/udp

Any ideas?
