Hi all- I decided to put my linux box (FC2) in the DMZ and test the defenses.....I am running Core 2.6.8.1 and for the firewall, I am using FS 0.9.3. Well....upon checking it late last night, I noticed all the traffic (non stop) coming in...checking the logs, the traffic was coming from a variety of places.....different IP, hitting different ports.....I assume testing different services (according to the logs). It was the amount of traffic that I found annoying. The only services I had enabled in the firewall was http, https NTP and DNS. I didn't check anything else. This morning I checked the firestarter archive site, I noticed posts about enabling ICMP filtering, which I did and I checked echo, traceroute, unreachable, timestamp and address masking. But I need to understand (half the battle is understanding) what was happening and why. Any pointers or direction you can give will help. I don't mind reading!!! Shadow
