OpenVPN Client Traffic gets lost

Starko

Hello,
we are currently on

2.3.1-DEVELOPMENT (amd64) 
built on Tue Apr 19 07:18:40 CDT 2016 
FreeBSD 10.3-RELEASE
NanoBSD-4G

We have a customer that is connected via OpenVPN. Our pfSense is the VPN Client. The Tunnel starts immediatly.
When I ping the host of the customer, I get a timeout.
Via tcpdump on the shell I can see that the host replys, but the reply never reaches me.

> ping 10.1.1.56 -t

Ping wird ausgeführt für 10.1.1.56 mit 32 Bytes Daten:
Zeitüberschreitung der Anforderung. (<- Timeout)

On 2.2.6 this worked. Can you help us?

It's there on the ovpn interface, is it there on the internal interface where 192.168.23.97 resides?

I'm sorry, the error disappeared after another reboot. Forgot to close the topic. Thanks for your answer.
