Sometimes no VPN connectin possible
Options
sometimes if i make a vpn l2tp connection with my usg 1000 , the client connects , but after logout en trying to login again it fails , this happens every time after a succesful login.
after 3-4 attemps it seems not possible to login again on the same internet connection, if i switch to another internet connection i can make the connection ! the client is a windows 10 pc , can this be fixed ? , is this a client problem or a zywall problem ?

I guess the symptom should able resolved by 330AQV8ITS-WK41-r74145.
My device is running on 3.30(BDS.7)ITS-WK49-r66311 which released at Dec 2015, and there is no this problem.
BTW, I suggest backup your startup-config.conf before you upgrading firmware.0 -
