Hi,
after updating my Raspberry Pi installations from stretch to buster i´m unable to establish my vpn tunnel. Before the tunnel was established without problems.
On the client it looks like ok at first
Wed Nov 24 23:12:16 2021 us=71085 Initialization Sequence Completed
WrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrWrW
In this situation i can´t ping the opposite tunnel-device. And after a minute it disconnects
Wed Nov 24 23:13:15 2021 us=651682 [server] Inactivity timeout (--ping-restart), restarting
Wed Nov 24 23:13:15 2021 us=653613 TCP/UDP: Closing socket
Wed Nov 24 23:13:15 2021 us=654571 SIGUSR1[soft,ping-restart] received, process restarting
On the serverside i see the following error
RWed Nov 24 23:13:13 2021 us=352624 client1/192.168.101.105:42100 MULTI: Outgoing TUN queue full, dropped packet len=42

Nothing is changed after the upgrade. Is there any option to extend the "TUN queue"?
Thanks for your help!
