First you are in the wrong list. Second check right now that the maintenance password of your router is not still set to the manufacturers original default. Third, SCO and Linux based firewalls are no challenge to a skilled cracker, so they will be through them very quickly. Fourth, suggest the following in the part of your diagram which says firewall: Screend running on BSDI Unix on a 386 or 486, with all non-essential binaries removed; connected to a TIS Gauntlet or Black Hole or Janus firewall; connected to a Cisco or Wellfleet or Eagle router, connected into your internal network. Now that is a challenge, multiple layers of difficulty, running on different operating systems.
