I'd recommend just the opposite, since as you said, it breaks "something", and if you believe you are "stealth", you're only fooling yourself. IMO, it's not worth it. My favorite firewall configs reject TCP with RST, UDP with icmp-port-unreach, and other protocols with icmp-proto-unreach. I think it's easier to make your firewall invisible than it is to make your host invisible. You can't disappear; the best you can do is become uninteresting (no open ports). good times, Vineet -- http://www.doorstop.net/ -- Microsoft has argued that open source is bad for business, but you have to ask, "Whose business?
