Question about port for NSLOOKUP

[hostmaster]

Hi.
I've been using Bind for NT for about 5 years now and use to participate in
this list but lost track of it for awhile.

I have a question I hope someone could help me with.  I'm trying to block
"unused" tcp/ip ports on a server.  I'm able to successfully do that and
leave port 53 open for DNS.  However, it appears that nslookup stops working
and can't find the "default" nameserver.

Question:  What TCP/IP or UDP port does NSLOOKUP need to operate on besides
port 53?  Does anyone know that.



Thank You very much.
