>In order for me to test an application running on a desktop computer from a tablet I need to bring the Home or Private Network Firewall down. Basically when you go to Windows 7 Turn On/Off Firewall you have two networks:

>Home or work (private) network
>Public Network

>My understanding the the former one (home network) is the LAN - after my internet router. This is the one I shutdown. Do I understand that a hacker would have to hack through the router to get to this network? I thought that since I use WPA-PSK security on my router, hacking is unlikely. Am I right?

If not necessary for the test unplug the line between router and external net ;-)
