So, I've set up a new router, enabled ssh and set up PPTP, but am unable to access any the router remotely.
I have one other older router that works perfectly and looking at it the only main difference I see is that although it is also set up as a Router, there is a Bridge interface on it. Out of curiosity I added a Bridge interface to my newer router to see if that would make it work, but it actually ended up blocking all traffic, so I removed it.
To be honest, I just don't see what having a Bridge interface should matter. I can ssh to the device within the LAN, just on the external interface. What am I doing wrong?
