Provided my lack of networking knowledge, I've been struggling with this issue for quite a few days now :

I have a QNAP-TS212 NAS on which i've created a shared-folder (mostly excel files). All the computers in the local network (windows) are able to access it without any problem.

Now, i want to access that shared-folder remotely (windows client), so :

1. I enabled OpenVPN (and PPTP) in QNAP admin.

2. Installed OpenVPN on the remote client.

3. Applied the configuration file that the QNAP generated - Configuration (openvpn.ovpn) :

   client  
   dev tun
   script-security 3  
   proto udp  
   remote  ***MY_WAN_IP***  1194  
   resolv-retry infinite  
   nobind  
   ca ca.crt  
   auth-user-pass  
   reneg-sec 0  
   cipher AES-128-CBC  
   comp-lzo  
   

4. OpenVPN connect successfully from the remote client.

5. Now, here's my problem : I can ping the NAS (got IP 10.8.0.1) from the remote client, But when i try to map-a-network-drive, i don't see the shared folder or the NAS or any of the other computers in the network...

   I checked - all computers are in "WORKGROUP" workgroup.

I'm probably missing some basic knowledge, So - any help would be greatly appreciated !

Many thanks.
