What are the Windows 7 Pro Firewall setting for VPN Ports and Mapped drives?

I have 3 sites connected via VPN through SonicWALL TZ210 and TZ100.
The PC behind the TZ210 is the main Data storage PC (Win7Pro).

The two other SonicWALL TZ100's have a (Win7Pro) PC which needs to have Mapped drives to the Data storage PC.

All mapped drives are Offline Syncs (and sync every hour as by default.

Recently I have had issues with one of the sites PC's not being able to sync with the the Sata storage PC.

I think it may be the Firewall Ports for the VPN/Mapped Drives.
This PC doesn't connect via PC Name and the mapped drives are by IP Address.

The other PC is OK but there are so many Inbound & Outbound Ports to go through I cannot marry them up easily.


Can anyone give me the correct list of UDP and TCP Ports I need to confirm are Open for Inbound and Outbound in the Firewall?

APOLOGIES for the delay my EE account had to be updated.

Which from your list are Inbound & Outbound Ports/Rules?

Is there also a port(s) that need to be opened for the Drive Maps?

these all are inbound ports......or else you can allow the same for both direction.

you can open netbios ports(137,138 445) and netbios ssntcp and netbios ssnudp(139)

allow all these and try your drive mapping.
