I don't know about redhat, but on my slackware box, I just have 

echo "1" > /proc/sys/net/ipv4/ip_forward

in my /etc/rc.d/rc.local (actually in another script for firewall, but invoked from 
there at startup)

Dear all

Thank you for your help ~^|^~.

I have checked the setup after read you meassage. The
file " /proc/sys/net/ipv4/ip_forward = 1 " when PPP
has setup. So, Does this meaning IP forwarding has
been involve in kernel and invoked? I still checked
the selection of "make xconfig" in the kernel. There
isn't the item named " ip forward " in "advance
router" in kernel 2.2.8 xconfig file. Do I need to
reload the kernel?

I have try to ping from my win 95 end to other PC
through my Linux and check the ip package by command "
ipchains -v". I can see the forward package courter
increased 4 if my win 95 sent out 4 package. But Why
there is no package forward back. If I ping from my
Linux which the same IP it could response. Do I have
choice the "IP masqerade". I not so familiar with IP
masqerade with "ipchains". I want all the service
could be use by win95, not only http but also telnet,
ftp and etc.

Thanks again
