I have a MIkrotik 450g router connected to a PPPoE static IP at one location. I have another Mikrotik 450g router connected to a PPPoE static IP at another location. I'm wondering how to VPN these two routers together. I have a camera server at one location and all of the cameras at the other location. I'm wanting the cameras to connect to the server through the routers. Does this make any sense and will this work?
