I know that since SMB is not secure, opening port 445 on firewall makes your computer vulnerable. To secure my connection, I want to run a SMB mobile app via SSH. Would I still need to open port 445 on my router to enable SMB? Would my host computer be protected by running SMB over SSH?

Not exactly the answer to your question, but did you consider sshfs? It exists for Android, play.google.com/store/apps/… –  MariusMatutiae Nov 27 '13 at 18:38
I am not sure if I understood the question. But: No, you make connection to your host computer via SSH. Forward the port over a tunnel to your device. And connect locally on your device to port 445. So only port 22 is needed. –  Edgar Klerks Nov 27 '13 at 20:11
SSH is not a good choice for this. Get yourself a real VPN tool that gives a full IP link. –  Zoredache Nov 28 '13 at 0:47
Thanks for the reply. Would I still need to open SMB port on my router? –  synthesis Nov 28 '13 at 11:19
