I have a bunch of RPI's running as web-servers at home. I can connect to one of my RPI's(RPI-1) via VPN and it can see the other RPI's on the LAN. From my VPN connection I can see the website hosted on RPI-1 but not the other RPI's websites(Because they are on the LAN and not connected on the VPN).
Is there a way that I can use RPI-1 to do port forwarding? Making RPI-1:9000 point to one of the other RPI's on the LAN?
