TomatoUSB

I apologize if this questions has already been answered. I have searched multiple forums to no avail. I am wanting to be able to remotely access all four drives on a NAS device behind my router using SSH with public key authentication. I am able to authenticated and access the router remotely, but the only method that I found for being able access the drives in the NAS is by using CIFS. I am alright with that, but the Tomato Shibby firmware that I use only has an option for setting up two CIFS.

Is there a way to add more CIFS? If so, how?

Is there an alternative and/or superior method of accomplishing my goal?

Thanks in advance for any guidance.

Your question is probably getting answered quite a bit in the other thread. The gui pretty much is limited to two cifs mounts. You can do some manual mount on your own though.
