Good point. I guess I should be more specific.
Basically, I have been working with *BSD firewalls for a couple of months now. I have used PF and IPF.
I wanted to learn Linux firewalls so this is where I am at now.
In a nutshell, i'm trying to find out the basic requirements to get IPTables setup and running on boot. For example, in OpenBSD, you needed to turn on a couple of services to enable PF and NAT. I was trying to find the equivelents for Linux, specifically RH.
Soo, basically, I was trying to find out what services I need to turn on that. That is why I was asking about;
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/ipv4/ip_dynaddr
Am I correct in assuming that so far?
Now I need to learn how to build rules and specify my interfaces.
All help and input is greatly appreciated.
