customizing Redhat firewall

[Adam Myrow]

Hi.  I now have both Slackware and Redhat on my system.  I had heard loyal 
Slackware users bashing Redhat for its hand-holding and loyal Redhat users 
bashing Slackware for its complexity.  So, I wanted to try Redhat to see 
how it really compared to Slackware.  Well, although it recognized my 
AWE64, it couldn't correctly install it and I wound up compiling a kernel.  
This was no big deal, since I took out stuff I didn't need anyway.  The 
only surprise was when I discovered that Slackware's preset firewall uses 
ipchains instead of iptables.  I had to compile again because I had used 
iptables support.  Anyway, now I've got the firewall up in Redhat, but I 
want to customize it.  I can easily run the setup utility and pick high, 
medium, or no firewall.  Yet, when I select "customize," I just get the 
setup menu again.  If I select no firewall and select customize, I get the 
reasonable response that you can't customize a disabled firewall, but no 
response in other settings.  So, is there a way to access the 
customizations in text mode?  Or am I just better off writing my own 
ipchains or iptables script?  Thanks.
