Windows 7: Share folder outside own LAN

29 Nov 2012   #1

Windows 7 Professional x64
Share folder outside own LAN

We have some computers in a lab that are in a different LAN than the computers in the office:

Office LAN:
Lab LAN:

From the Office LAN I can access shared folders on the Lab LAN computers by mapping them as network drives.

Now I set up a new computer in the Office LAN and shared a folder. Everybody in the Office LAN can see and map that folder.

But the computers in the Lab LAN cannot.

How can I allow the computers in the Lab LAN to access the shared folder from the Office LAN computer?

I know this can somehow be done, since I can access the shares in the Lab LAN. Unfortunately the person who set that up is gone now...

I probably solved it. Routing from Lab LAN to the Office works, Office -> Lab not.

Hello all. The title doesn't make sense, as I had to abbreviate it. I was just hoping that someone could tell me whether or not there's a fairly simple way to share folders from my computer with someone else over the internet, in the same way I can share folders with other people in my...
