Please check that all modules are compiled. To confirm that (1) Boot with kernel 2.4.21 . (2) Save the output of lsmod to a file. (3) Reboot with kernel 2.4.30 . (4) Save the output of lsmod to a file. (5) Compare the two files. If any modules are not loaded, try modprobe to load modules manually. If you have all necessary modules compiled, then netfilter user mailinglist would be better place. http://www.netfilter.org/mailinglists.html#ml-user Good luck. -- Kernelnewbies: Help each other learn about the Linux kernel.
