Considering both machines are connected to the router independently (that's what you say you want) the 2 solutions in principle are:
1. See if you can configure the router so as to allow Internet to the one and not to the other. Should be in the manual.
2. Uninstall the TCP-IP protocol from the other machine and use a non-TCP-IP protocol (such as Netbios) for the file transfer.
But if you want to use that machine as file storage only a viable alternative is to replace it by a network-enabled disc. Just a disc with an Ethernet-connection. Perfect for file storage and by definition it can't do anything more. Just what you say you want (but maybe it's not what you really want.
Or use an external hard disk connected to a USB-port of that 'other' PC. Also: file storage only.
Hello! I want to connect 2 winxp machines via a EBR-2310 but i only want one machine to be able to access the internet. I want to stop the other machine from accessing the internet completely.
I want the internet machine to be able to transfer files to and from the non internet machine.
In other words i just want to use the 2nd machine as file storage only.
Thanks in advance for any help.
