Unable to Access shared folder from Client

Hi,

I just recently activated the OpenVPN but i'm having some trouble accessing our shared folder once our OPENVPN client's are already connected, they were able to browse over the internet and I can see on my firewall appliance their IP Address since I enable Full Tunnel. Pinging the Untangle's internal IP address is not a problem but else cannot be ping, not sure what else needs to be done.

- Site->Client
- Pool: Default, IP/Netmask: 172.16.0.0 /24,
- Full Tunnel = True, Export DNS = True
- DNS Override = DNS Server IP

Cheers!
