I’ve been asked link two schools to together so we can have a mapped drive. However, they are 3 miles apart so a fibre link is impossible. They are both on LGFL and have 40mb connections. I thought maybe I could link the servers and have trusted domains through LGFL. I’m not sure of the best way to approach this? What IP and ports would I need to request Atomwide to open? Thanks in advance.
