Hi Gyula，
Thanks very much for your information!
I reproduced this case. If vpn client close abnormally(for example,close tunnel without clicking close tunnel button),
after reconnecting vpn ,will display tunnel connection is normal, but the traffic can't pass through.
If that happens,you can use the following two ways to reconnect:
(1)On VPN Client,use "close tunnel" button close the tunnel firstly,then reconnect the tunnel.
(2)Go to device "VPN->Connection Status->IPSec VPN Connection Status",disconnect the tunnel firstly,then reconnect the tunnel.
Thanks,
Dan
Hi Dan_Z,
thank you very much for your answer. If I try to reconnect I can, but I no longer access remote LAN.
As I see P2 renewals works without any problem (after every approx. 1000 seconds), but after the first P1 renewal (approx. 3400s) something goes wrong, after it client can't access remote LAN.
To debug this I specified in VPN Client at "Traffic verfication after tunnel opened" an IP address.

What can causes that DPD works but I can't access remote LAN?
