Graham, Assuming you've built ip_tables into the kernel (not as a module), then I'd be interested in learning the difference in the process you used to install iptables between versions 1.3.5 and 1.3.7. Version 1.3.5 works fine for me with kernel version 2.6.20 built in (not as a module). But when I use the same install process for 1.3.7, I get the error messages. And when I go back and configure ip_tables as a module, then the error message goes away, which is what one would expect. Thanks, Harvey
