Hello. I'm using Slackware 8.1, kernel 2.4.18 and iptables v1.2.7a. I blocked external acess to some services using the following rule: iptables -A INPUT -i ! eth0 -p tcp -m multiport --destination-port <port1>,<port2>,<blablabla> -j REJECT However, when I perform a stealth scan using nmap on my host, I still can see them running, but instead of "opened" I get them as "filtered". Is there a way to block these results, making the services literally invisible ? Appreciate any help, and also any technical information (links, docs) regarding the answer. Julio Cesar Ody
