I'm slightly confused by the word 'optimise'. Do you mean that nothing at all is happening? In which case 'sysctl -w ip.forwarding=1' (as root, at the command line) should get things moving. You can automate this by editing a line in /etc/sysconfig to say # If you want this host to be a gateway, set to YES. gateway=YES and re-booting. If you mean it works, but it's slow, I would have thought the hardware was more likely to be the problem. Can you tell us what kind of ethernet card and serial port you have? > Is upgrading to a 486SX a good move? Possibly, but I would expect a 386 to be able to cope with this under a reasonable load. Is this machine being used for anything else? > Is adding more memory (from 8 to 16Meg) a good idea? 8MB should be plenty if you're not running X. (Assuming you've got a reasonable amount of swap - say 16M). -- James Raynard, Edinburgh, Scotland jraynard@dial.pipex.com james@jraynard.demon.co.uk
