Is something wrong (iptables) with Linux-2.6.21-5?
 

It was ages I didn't recompile a kernel, everything was all rigth with the usual distribuition I used. I'm actually using openSuSE 10.2 with the kernel 2.6.18.2-34 and I was sharing an internet connection (just for fun) with:
______________________________________________________________________
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
______________________________________________________________________
I wanted to try the kernel 2.6.21-5 and making the xconfig I did not make a mess, but the module iptable_nat look like disappeared! I must be a frog that need a kiss from someone that knows things better than me. Please give an help.
Ciao

Well did you check out that the "missing" module is in the kernel, compiled in or as a module? And if it's a module, did you try loading it manually with modprobe?

Well . . .
 

I did as you said and during the most important task of the "recompiling a kernel" I forgot a module: CONFIG_NF_NAT. It was my fault.
Thanx again. Ciao :Pengy:

CONFIG_NF_NAT didn't appear in kernel 2.6.21.4
 

Dear all,

I meet this problem too, but on 2.6.21.4.
I didn't see CONFIG_NF_NAT option in .config file.

Could you tell me that this option is lie on which catagory,
if I use "make menuconfig"?

Thanks very much
