After I ran the command and changed the gateway in the
windows system to 192.168.0.10, I could ping
192.168.1.5 and 192.168.1.1 from the Windows system.

However this command does seem to work - I can run the
command - but there is no result(is there suppose to
be a response?)

Anyway, I cannot access any sites from XP system. Am I
supposed to change the proxy of the browser in the XP
or something?

Another thing - I run apache server(I am a web
developer) on the linux system - will this be a
problem? A strange thing is that I cannot access the
apache server on linux from the XP system. Ie.
'http://192.168.0.10/' gives the listing of the
document root in the linux system - but I cannot get
it if I try to access 'http://192.168.0.10/' from the
windows system.

Thanks for all the help.
