I ran into this problem myself.<br />
I recompiled the kernel checking so that I answered all questions right. I use make zlilo to compile and install the kernel into lilo right away. After this I booted and booted once again :)<br />
Now on /proc/net a few more files showed up :)<br />
They were missing before :) (ip_forward among them aothe rimportant for IP fw:ing). Dont forget to install ipfwadm program and its header files before you compile the kernel.<br />
<br />
Good luck!<br />

Recompiling is the first thing that comes to mind, and I have done it over and over again. <br />

I am settint up a firewall with IP masquerading. I have followed the HOWTO and compiled the kernel with all the required options. When I follow the HOWTO, I get to a point, where I am supposed to issue the following command:<br />
<br />
ipfwadm -F -p deny<br />
<br />
At this point I get the following error message:<br />
<br />
ipfwadm: setsockopt failed: Protocol not available.<br />
<br />
What does it mean and how do I fix it?<br />

setsockopt: Protocol not available - what's that?
