[lug] Over my Head in a Puddle

[Bill Thoen]

There are actually 3 servers involved here, plus the modem whch has the works built in.  So I think I've got this setup:
                  INTERNET
                        |
                       DSL
                        |
             ----Wireless Modem---- 
             |                    
          Wireless         Wired Switch Ports
            |                            |     |      |.          eth1 ----------------+
        Windows Laptop       |.     \.    + ------eth0---GISNET      |
                                        |        \.                      SERVER.    |
                             Cisco switch.   ELEVATION.                    |                    
                                        |.           SERVER.                 D-link 
                                  VFARMS.                                    Switch
                                   SERVER.                                    |.     |
                                                                      Workstation 1  |
                                                                                             |
                                                                       Workstation 2


(an iPad is not a very good graphics renderer. Even text graphics!) so how does that look. When I can get any of these machines to connect with email I can do a better one. But do you see any totally wrong things?
