I have a remote server on a remote network in a vacation house location. The router is presently forwarding port 8765 to port 8765 on a remote network pi. The sshd daemon on the pi is set up to accept both port 22 & 8765 connections.
On the above remote network pi, there is a web application I'd like to access. Port 8765 is the only port I have forwarded on the router and I do not have remote access to the router. Also it is many miles away and not possible (at this time) to access it locally.
Is there a way I could set up a temporary redirection (port 8765 to 80) on my remote network pi to allow me to use my remote pi web application?
