I've got the first Ethernet port as WAN, second Ethernet port as LAN1, and the remaining ports as LAN2. I have an L2TP VPN instance running on the router that is evidently used by both LAN1 and LAN2....

@DarrenM89 Look into DDNS, it is a clever way of dealing with keeping track of changing IP addresses. It is a separate independent service that simply let's you specify a unique url for a person's IP...

@DarrenM89 I am getting the same thing with L2TP on my Windows 10 machine, but I can connect successfully to PPTP on that same machine.
