Accessing Windows File Share via Remote VPN

[Nigredo]

Hi All.

I configured VPN access with use of Endpoint Security client for remote users to my LAN on the firewall [R81].

There is a file share on MS Windows 10 PC, which remote users should be able to connect to. After successful VPN connection I can ping that PC, access it by RDP, but cannot open file share nor from Windows OS neither from Mac OS - "the resource can't be found".

I can see nbsession (TCP/139) and microsoft-ds (TCP/445) services in the log.

Could anyone help me to solve this problem?

Thank you in advance.
