I have recently setup a VPN router (raspberry pi running openwrt) that sits between my modem and router. I have a server that is attached to my regular router that I would like to access from outside. I understand that I could probably accomplish this by setting up some port forwarding. However, I believe it may also be possible to provide the secured access to this server by way of the vpn router I have running.
Am I on the right track here - can I leverage the vpn router running on the pi to provide secured incoming access? If so, where might I find some instruction on how to set that up?
