Need help to setup SMB access in SSL VPN rule

Figure: How I added new SMB Service

Hi there, 

I am a new XG210 Adminstrator (less than 1 week).

Previously I used Watchguard and Fortinet Firewall.
Changed to Sophos upon frens recommendations. 

The interface is pretty straight forward and I managed to implement my own rules for 2 ISP connections,
as well as a SSL VPN tunnel where users can be authenticated to login to our Network. 

Initially I set All Services to allow between remote users and my Network,
but now I want to restrict, after all they only need Http and SMB access.

HTTP is ok, but I wasn't able to find SMB under Services, 
so I created this service and added ports 465, 135-139 to SMB service.

But my users are still not able to access our Shared folders.

Can anyone help?

Thanks in Advance
