Are you sure? Because NAT does not change the packet size. If I don't
change the MTU of the Unix boxes behing the router, they have
problems, too (connecting to FTP servers work, lsing a large directory
hangs, etc). This fact is widely known and documented. See for
instance <URL:http://www.linuxdoc.org/HOWTO/DSL-HOWTO/tuning.html> or
the URLs I gave.

The MTU of the PPP link (1492) seems fine, the router itself has no
problems. And remember, only MacOS has problems.
