VPN Tunnel established but no communication possible, need help
I found following article related to using a vpn through a fritzbox, maybe someone can see a related issue.
Using the FRITZ!Box's Internet connection with VPN software from another manufacturer
You can also use VPN software from another manufacturer to establish VPN connections to a remote VPN server over your FRITZ!Box's Internet connection. Since VPN Passthrough is enabled by default for the VPN protocols IPSec and PPTP, no additional settings are required.
If the VPN software uses the IPSec protocol without NAT-Traversal or the PPTP protocol, the following restrictions apply:
Simultaneous connections from multiple VPN clients in the FRITZ!Box home network to the same VPN server are not possible.
The IPSec operating mode "Authentification Header" (AH) cannot be used.
As the VPN software does not notice the disconnection of an Internet connection, a new VPN connection to the VPN server will not be automatically established when a new Internet connection is established. This, however, is necessary as the FRITZ!Box usually obtains a new IP address from your Internet Service Provider when a new Internet connection is established.
Therefore, the FRITZ!Box should be configured to permanently maintain the Internet connection.
