Everything works fine but I get a lot of TCP Resets on the 33.3 router. The tunnel and bandwidth are stable. On the OpenVPN server there are no suspicious entries.

Sometimes I also get some SYN,ACK entries.

The server (10.1.0.1) sends TCP resets to the client (10.1.0.6).
What could be the cause of this behavior?
Could this come from packets they come too late?
Maybe some packets needed too long and new one were requested and they reached before?
