I suggest posting in your own language in the International forum section.

Because what you wrote doesn't make much sense ;).

Oh.. I forgot you were talking about iptables, ehm...

Code: Select all

iptables -I INPUT -s 0/0 -d 0/0 -p icmp --icmp-type echo-request -j REJECT

but actually I suggest using the "block everything except related traffic, and allow certain ports" aproach... that's much more secure and it's a neat iptables feature (ipchains didn't have it).
But I'm not going to help you with that, just google.. I'm sure there are plenty of easy firewall scripts ;)

Yeah. There is one thing I can't help wonder about....

How can you trust this firewall setup if you have absolutely no idea what it actually does ?

Is it really closed or just telling you that it is? Linux, but also netfilter, is more extensive than you may realize.
