I'd be interested to know if you can use FTP from your Linux box to the 
outside through the Linksys router.  One of our staff can't get to our FTP 
server from home through his Linksys router, although other folks without a 
router can.  Our server terminates the connection, leaving this error message 
in the logs:

ftpd[31488]: getpeername (in.ftpd): Transport endpoint is not connected

It's the 'getpeername()' request that's failed.
