Hey so, I finally got to this and I did the following:
I went to System > Routing and setup a new gateway
10.1.4.13 -> This didn't work when I went to the status tab it showed this route as offline so I changed it to (FYI this is the current IP assigned to the DreamMachine WAN Port)
10.1.4.1 -> This immediately showed as online
I then went into Static Routes and did the following:
Add -> Destination Network 10.1.1.0 / 24 -> Gateway 10.1.4.13 -> Didnt work tested with ping and VPN no response. Then did
Add -> Destination Network 10.1.1.0 / 24 -> Gateway 10.1.4.1 -> Got a response through ping but seems to be redirecting and I cannot see the machines in VPN
