From what I recall, you're right Tim. The problem comes when you have a larger MTU under FreeBSD than Windows can cope with by default. What ends up happening is that the packet sizes are too large for the Windows machines and so you have data loss between windows machines using FreeBSD as a gateway etc. Cheers, Marc On Thu, Nov 09, 2000 at 12:42:33PM -0500, Tim McMillen wrote: > > That may be how you do it, but correct me if I'm wrong, it's not a very > good idea.
