[plug] routing problem

[Jon Miller]

Can't figure out what the problem is but a client reported their access to the internet was down and when I went to look into it I found the router had been reset to factory defaults.  I configure this and the router was able to connect to the ISP.  I can ping from the server to the Internet and all is fine.  However, when I try to ping from a clients PC (Win2000 Pro), I can only ping the server (Debian) on the internal interface. Cannot access the Internet from any workstation.
Can anyone shine some light on the subject?

     Router  
        |192.168.1.254
