Port scanning

[sathish]

Hello Linux team!!!!

I have done masquerading in redhat9.0 to share the net to the windowz clients, in windowz client i have installed sygate personal firewall, in that frequently i am getting this message which is logged by sygate firewall

Somebody is scanning your computer.
Your computer's UDP ports:
33453, 33454, 33455, 33456 and 33457 have been scanned from 129.41.54.49.

Now my question is how to avoid port scanning, what code to be put in iptables.. to avoid such things in future...

thanks

Sathish.

hmm..

There are lots of premade firewall script available for iptables, or use firestarter

That's right you can use Firestarter.  It is a good firewall and you can avoid port scanning.

Good luck!
