Hi everybody,

I have just installed Redhat 7.1 on my PC, while I was choosing options to customize Redhat configuration on my box, I found it has a option to setup a built-in firewall in my computer ( high, medium and no rule option ).

So I would like to know about this firewwall's mechanism, I mean what is automatically set up on my system ( what programs is used and configure them ) ?

And how do I have to configure the same work my self instead of this utility implementing it?. Could you tell step by step to implement this task.

Any help would be highly appreciated.

Hao Dr
