I'll make this short. I'm running RedHat 7.1, kernel 2.4, and iptables with MASQ modules. I'm having trouble understanding the flow of a packet coming into my box, so I'm confused as to which chains to use. Since my packets are MASQed, does that handle the forwarding for me, and all I need to use is INPUT/OUTPUT...or do I need to use the FORWARD chain too? I'm trying to get POP3 and FTP (on high ports) running...maybe understanding the basics will help me understand what rules I need to make.
I've scoured the net and HOWTOs, still don't fully understand the flow. Thanks everyone! _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
