I think the iptables will work. You could try to list the rules you have in
place at the moment, iptables -L.
Looking at the manual page, what is the mangle table?
Cheers,

hi guys ,
I want to ask you , about the Iptables configurations
...
When I run nmap ,it says me that I have an specific
port open ...
When I do a web test of open port at
http://scan.sygatetech.com/prequickscan.html
Its says me another ports open or closed ....
when I run netstat it says me another completely
different thing ...
I dont know what to trust ...
for example I want to close the udp port 111 and icmp
8 . Can I do this for example in the terminal :
./iptables -A INPUT -p udp --dport 111 -j DROP
and the port will automatically be closed ?
or should I restart the machine ?
thanks in advance ,
