Windows 7 Firewall Question with Peer to Peer network and VPN.

Posted on 2014-12-18
Last Modified: 2014-12-28
I have two small peer to peer networks at separate locations connected with a SonicWall site to site vpn. I have a Windows 7 Pro machine at one location that I have a shared folder on that users use as a "pseudo" server. I would like the users on the other side of the vpn to have access to that folder but Windows 7 is seeing that network as being a public network and not allowing access to the shared folder. Turning the firewall off on that machine allows access but that's not an acceptable solution. Is there a way to allow or to tell Windows firewall the other network is private or trusted ?

if it has a static ip address you can allow that address in the firewall settings

Your easiest fix is to change it to a Work network instead of Public.

Both sides are set to work, it appears since they are on different subnets across the vpn it is seeing the other side as public.

What would I allow through the firewall ? Can I set an exception to allow the entire subnet for the other side of the vpn ?

Here is an article that deals with this.

It's a matter of setting up firewall scopes for File and Printer sharing rules that are already there.
Just add the remote subnet.

Yes you can.

Go to Control Panel > open Windows Firewall > click on Advanced settings on the top left corner > click on Inbound rules in the Windows Firewall with Advanced Security window that appears > locate the File and Printer Sharing (SMB-In) entry on the list that is assigned to the Public group and right click it > go to Properties > go to the Scope tab > in the Remote IP address box, click on Add > in the This IP address or subnet field type in the subnet for the remote network (e.g. > OK > OK when done

It seems to me that SMB-In is only one of the firewall rules that might be productively changed.
As in the instructions I provided.....

Nothing personal, I saw both solutions and was prepared to try them both. I tried the other one first because it was one paragraph and it worked so I gave him the points. Thank you both for responding.
