One-way file transfers to guest network?

[JaimeZX]

Greetings!
The setup: I have my LAN with "trusted" machines, and two guest wifi networks for less-trusted devices. Plugged into the router is an external HD with pics, movies, documents, etc. Of course right now that's only visible to the LAN via a Samba share.

Is there a way to make that same drive (or a subdirectory thereof, even better) read-only to a guest network? It'd be convenient to be able to browse files on the less-trusted devices without risking contamination.

Thoughts?

OK - follow-up in case another user is trying to figure this out. This one was straightforward. I thought that Guest Network > Allow Access to Intranet > No would take precedence over the USB Application > Network Place > Samba > Allow Guest Access > Yes... but I was wrong. This was allowing guest network write access to the external, which obviously I didn't want. The solution was simply to turn off Samba > Allow Guest Access and create username/password requirements.

Of course now the challenge is having to move all my stuff into a single folder because (in Windows) you can't map a drive letter to an IP, it needs to be a directory inside that IP. Oh well!
