How to check kernel (RH9) is support for Internet connection sharing??
 

Hi, everyone,
I have 3 computers and a hub, I tried to setup me linux box to share internet connection of RR. I also searched the solutons on internet and tried for a long time.
After all, I decided to recompile the kernel.
My kernel is RH9 2.4.20-18.9
also I did every thing like
changes the /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.ip_always_defrag =1
add in the /etc/rc.d/rc.loacl
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/ipv4/ip_always_defrag

and also do the NAT sutff...

so I compiled the kernel and tried the suggestions I searched on WEB,
however, I compile the kernel and can reboot with some USB problem. (I think it's not matter!). When I input the command
# cat /proc/ksyms | grep ip_forward
I got notthing? (The HOWTOs I found says I shoud get someting back like
00141364 ip_forward_Rf71ac834
So, I wonder is there anything wrong? or I should choose specially when compile kernel?
And, can anyone tell me how to check the kernel is fit my requirement after compile so that I can make sure the kernel can do the internet connection sharing and figure out the problem is not on the kernel.



Thanks for your help
