2 quick questions. 1. I'm running a DNS server for my internal LAN..but I do not want people on the outside using it. Will using IPFW to block INCOMING tcp/udp to port 53 prevent DNS from working? 2. I understand how you block an IP and even a CLASS C...but what about a DOMAIN? Here's what I mean specifically. Let's say I want to DENY a BIG site from accessing my machines. Let's for example use microsoft.com. Well simply IPFW deny'ing microsoft.com, will get only 1 of their Class C's..when microsoft.com has tons of IP Blocks. Is there anyway to block a domain short of figuring out each and every class C an ISP has? Thanks.
