Provided that these IP addresses are routed to this machine by your ISP then
this is a simple matter of setting up the proper rules. As you are running
RH 7.1 you have the option of using either ipchains or iptables for basic
firewalling and/or routing. However, for what you are now looking for you
will need to use iptables. Ipchains can provide this functionality, but the
ipchains support provided with 2.4.x kernels is not a complete ipchains
implimentation, it's actually a wrapper. My iptables firewall script will
do everything you listed in your original posting. You can get my script
from http://www.asgardsrealm.net/linux/firewall.
