I know this may be a rediculous question, given the audience, however, I 
will inquire anyhow.

"Have you verified that your kernel has installed cleanly?" 

I am still on 7.2-Stable, on my production servers, however, when I have 
attempted hasty upgrades, and reinstalled the kernel after compiling it 
on the new system, it required a second iteration of cleaning, and 
recompiling/installing for the kernel to recognize the net options that 
are being referenced.

Hence, when I initially compiled and installed the kernel, I had to 
repeat the process a second time, to see all firewalling activated 
correctly.(pipes, and other rules)

Of course, as previously indicated, this may be just a new bug for the 
newer system, however, I would try that first. Also, make sure you port 
the new version of your rules/config file to the 8-Release branch. I 
have had trouble going between 6 and 7 with some of these rules not 
being recognized but the option compiled.

I can't remember what that was, for a good example, however, just a few 
things to investigate.

I apologize if these options have already been investigated.

Respectfully,

Martes
