Is it possible to open port 445 when using L2TP connection?

Question

Computer networks

2 offices, between them raised L2TP, opened a port for rdp, but there is a need to give access to the share, as I understand it, port 445. How to deal with recent events. Can it be opened or is there some other way?

Answer 1

You can open access within these two local networks via l2tp.
Another point is it necessary? Besides the fact that this is still not very potentially safe, you will clog the channel.
As an option, synchronize the necessary folders via https://syncthing.net or install a caching FS BranchCache in another office, but allow transmission only over the VPN channel.
