can anyone help me figure out how to SSH into my raspberry pi in the following situation? I have an android phone using easytether connected via usb to the pi, then I connected the pi via ethernet to my wireless router's WAN port. I am unable to figure out how to SSH into the pi on the WAN side of the router from a PC on the LAN side. Do I need to setup a reverse tunnel or port forwarding? I cannot get it to work.
