how to compile redhat kernel 7.2 2.4.7-10smp to support iptables. I get an error while using iptables. How do I know if iptables has been properly configured on my machine

Iptables will install by default. You just need to turn it on. The easiest way to do this is to open a terminal window and, as root, type:

ntsysv --level 2345

Scroll down to ipchains, hit the spacebar (so that there is no asterisk next to it), and then scroll down to iptables and make sure it has an asterisk.

The easiest way to reinitialize all this is to reboot. (7.2 has some funky scripting that won't initialize this change without a run-level change.) Once you've rebooted the system, type:

service iptables status

and you should see a list of the current table rules.

You can do it manually by doing:

rmmod ipchains (if it's loaded)

modprobe ip_tables

use the iptables command to create your rules

use iptables-save to save out your rules as /etc/sysconfig/iptables

When the system reboots, it should load your rules automatically.
