FRITZ!Box 7530 Service

Cannot access shared files or printers over an active VPN connection

Although IP communication with network devices in the remote FRITZ!Box network is possible over the VPN connection, for example via ping, you cannot access shared files or printers in the remote FRITZ!Box network.

Simply proceed as described below. After each measure, check whether the problem is solved.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Using an IP address to access shared files and printers

You can only access shared files and printers over a VPN connection if you address the devices in the remote FRITZ!Box network using their IP addresses:

2 Allowing NetBIOS for a VPN connection
