SSH server that can be configured to only allow connections over wifi hotspot interface I shelled out for SSHDroid Pro and am quite disappointed that it can't be configured to allow connections over the Wifi Hotspot interface without also allowing connections from the mobile data interface (i.e. the open Internet).  Is there another SSH server app that can do this and is otherwise relatively feature-complete?
I use Servers Ultimate Pro to limit my server's (SSH/FTP/WebDAV) accessibility to Wifi hotspot's subnet (I use it on wlan0 or rndis0). The server cannot be mapped from internet in this way. Its very easy to use, even a newbie can setup a server on it.
