Great, that worked wonderfully!
So, just out of curiosity and for completeness, do you know why this
error would present itself only on SMP kernels? I'm presuming it has
something to do with what version of IPTables is compiled in the
kernel.
We need the extra .targetsize statement on kernel 2.6.20-1.2320.fc5smp
on an i686 but don't need it on a 2.6.15-1.2054_FC5 kernel on an i686.
Thanks for your help!
