Network off a network, but not a subnet mask

[Stephen Constantinou]

Dear Nils and Andrew

Thanks for the input

I disabled the firewall on the XP machine and tried again. 
Unfortunately I still could not connect to the XP machine from the 
laptop.  From the laptop I tried to ping 192.168.1.175, 192.168.1.1, 
192.168.1.2. but the host is always unreachable.

The XP file system is shared and when I put the laptop on the first 
network, the Smoothwall network, I can ping the XP machine, make a VNC 
connection to the XP from the laptop, and see and write to the XP file 
system.

I cannot think of anything else to do.

Any further help appreciated

Stephen
