I'm trying to connect a custom device on my LAN from the internet. There seem to be a bunch of guides on how to do this, but they all seem to be missing a step, and I can't seem to figure out what it is.
My setup: I have a device (raspberry pi) running on my LAN. It has a static IP 192.168.1.134. I can access a web page on the pi from my LAN through http://192.168.1.134/webpage.html. I have a router and a DSL modem. The router has a known IP address (23.X.Y.Z).
On the router, I've setup a NAT entry to forward anything with port 80 to 192.168.1.134. (When doing this, the router's website complained that it was moving it's external web site to port 8080...). As soon as I do, I seem to loose connectivity to the internet from the PC on my LAN. I tried accessing my website from 23.X.Y.Z/webpage.html, and that does not seem to work either. I'm wondering if anyone could suggest how I might go about this?
