I need to use TCP/IP filtering in my Windows 2000 Server for security
purpose
In my Windows 2000 Server I have installed DNS server also

So I have blocked all ports and and allowed only certain ports

I have allowed ports in the TCP are
25,53,80,3389,1433,110

The ports which i allowed in the UDP are
only 53

So this is the suiation

After i restrict the ports i am unable to browse the internet
My DNS server is unable to resolve queries
So i have planned to use this DNS Server also as a secondary DNS Server and
I am unable to Transfer zones

So after port restriction my DNS does not respond

can any one tell what addition ports should I add in the UDP
Or what should i do this to work but i need port restrictions

So is there any other way to sort out this problem so that my DNS responds
to queries

What should i do for this.Any one help me in this regard

Regards
Sabeer
