Jean,

I have the eaccess router. The setup manual tells you to filter ports 20,21
and 80 externally. You can verify what is open from the outside with the
following web page which will scan you if you give it permission.

You should also change the default password which the manual doesn't 
mention :( At least not that I could read in my poor Japanese.

If the only way through is to hack the router, then I can live with
that for the moment, since it's just my home machine. I'll get the
firewall up when I have more time.

Tom.
