Stopping a PC accessing the Internet ?
awemawson:
Thank you all for the various suggestions - however
I think several of the more recent contributors have perhaps not taken in the actual need - I want to access this machine from my 192.168.1.xxx network yet prevent it accessing the net AND still have 192.168.10.xxx connectivity for the 'Purelogic' ethernet break out board and torch height controller that are the "raison d'etre" of the PC.
...I think, (but have yet to be able to test) - adding USB WiFi link to the 192.168.1.xxx network with suitable constraints 'should' do it :scratch:

Andrew, just one query - EMC? I was a little worried when the PC was mounted in the fresh air and I wondered if, as its not in a complete Faraday cage, it might suffer with interference from the plasma discharge? I'd be concerned about the implications of a USB WiFi dongle or similar (i) for the interference to the link, although I guess less important if its only used for downloading DXFs etc. prior to cutting; (ii) if the USB device/cable will provide a route for interference to get back into the PC, as the PC's +5v rail is used to supply +5v to connected USB devices and the cable might act like a receiving antenna.

Dave,
The Compac USSF has a well shielded case and every thing hanging off it uses screened cable. I think it'll be ok but time will tell ...... :scratch:

Could you not just set the net mask to 255.255.240.0 ?
That would make 192.168.1.xxx and 192.168.10.xxx the same network.

Don't know PK - I'll try that when it's back together - thanks for the suggestion :thumbup:
