Hi all,

does anyone have resources (Howtos etc.) to help me set up 
firewalling under netBSD? The only help I could find was from the 
NetBSD.org homepage.

Now a little DNS topic: 

My ISP does not allow routing and NAT protocols and DNS servers 
to be run on the machine connected to the ISP and claims, that all 
UDP ports as well as some TCP ports (that as they say "are 
commonly used by hackers and programms like Back Oriffic") are 
blocked. Now I want to set up a caching only DNS Server on the PC 
used as router, AFAIK DNS servers exchange data by UDP, but the 
description I got from some books explain the Caching only DNS 
server as "storing current DNS requests for further use".

Now I wanted to know if a caching only DNS server uses UDP ports 
other than a standard browser does and thus the ISP could find out 
that I use a DNS server.

Thnaks in advance
