Router plus SME server for safe mobile client hookup
« on: March 19, 2006, 07:30:57 AM »
I have people that would like to hook up a portable for downloading email,   but I would like to have them off my secure network portion so they couldn't accidentally propogate a virus from a infected machine.

I was thinking something like this. The Vertical lines and hyphens represent wiring from a device.

      ADSL Modem
              |
          4 port Router 192.168.0.1  DHCP 150-254 (possibly wireless as well)
              |   |   |  |
              |   |   |  |-- Jack for temporary portable Computer DHCP
              |   |   |
              |   |   |----Jack for possible old computer for Web/email
              |   |          running ClamWin antivirus or perhaps a Linux          
              |   |          Workstation. Thinking perhaps to prevent webmail
              |   |          like hotmail access from secure side of SME server.
              |   |
              |   |-----possible printer hookup here if better than behind
              |              my server 192.168.0.101
              |
              |
              192.168.0.2 to world with SME network card1
              SME SERVER
              10.0.0.1 possible DHCP 10.0.0.150-254 using SME card 2
              |
              multiport Switch (8, 16, or 24 ports)
              |    |      |    |    |
              |    |      |    |    |
              |    |      |    |    |----Printer1 monochrome / scanner 10.0.0.101
              |    |      |    |    
              |    |      |    |--------Printer2  color / scanner 10.0.0.102
              |    |      |
              |    |      |----Workstation 1
              |    |                                                    
              |    |----Workstation 2
              |                    
      Additional Workstations  


Anyone doing something like this?
Would it work?
Recommendations?
Ports on Router for SME network server open for 80-Web, 25-mail,443-SSL other?

Any problems with VPN, Mail, Web, Secure Web?

Thanks, Ken
