Hi, 

 I'm new with Linux Redhat 4.2, I would like to biuld a firewall over Linux
but I'm afraid about it's security. If some one else have any experience 
about that, please send me any comment. Which package can i use?

Any comment about:
 -Socks Server
 -Smap Server
 -Or any other proxy server

Where to find it, etc...

Thanks for read it   :-)
