Just happened to have a test core/hybrid that was set up with a nas device on the external net that the test core was on, so I thought I'd give this a quick shot.
1st the
EASY WAY put the nas device or windows box on the internal net and let it get auto-detected like everyone says.
But if you are stubborn or curious like me.
I initially shut off the firewall but later tested with it on so the LinuxMce firewall should not have to be touched. (let me know if someone finds out otherwise).
1. In the web admin select show devices tree.
2. Select core from my devices.
3. Create child device - use the file server device template put in its ipaddress, username and password.
4. Now select the file server you just made and Create child device - use the windows share device template put in its sharename, username and password and save it. if you go the kde desktop open konqueror to /home/public/data/other and you should see some thing like Windows Share [55].
Now let it sync the files -takes a while.....................
You can go resync the files using the web admin but if you have a lot of files just let it sync overnight on its own.
In theory you may even be able to auto detect it on the internal net then change its ipaddress in the web admin and reconnect it on the external net.
But then again
