I just got done upgrading my home network server from SuSE 5.3 to SuSE
6.0 and all I can say is what a pain. The upgrade was very smooth and
everything was working fine after the upgrade expect IP Masquerading. As
it turned out, I had to go and hand edit "/etc/rc.config" and set
IP_FORWARD=yes inorder to get things working again. I guess I'm confused
as to what other way is there to configure this stuff?  I don't recall
seeing any option for IP_FORWARDING in YaST. I had IP Masquerading
working fine under SuSE 5.2 and it still worked after I upgraded to 5.3.
It seems like something really changed in SuSE 6.0 with regard to this. 

What alerted me to this problem that then led to a solution was that
during bootup, I would see a message stating that IP Forwarding was
being turned off. After greping around a bit I found that this message
was being displayed from the "/sbin/init.d/boot" script.
