    i am facing an issue with my VPN config. I have 1 central ZS, and two other ZS instances, and have configured LAN to LAN


    So the main point is ZS2 (configured as VPN server). The issue is, that time to time VPN drops without any reason (every 10-45 min)
    Here is the log:

    15:22:06 	Interface VPN06 is UP
    15:28:34 [Extern_IP] Inactivity timeout (--ping-restart), restarting
    15:28:34 /root/kerbynet.cgi/scripts/vpn_mii VPN06 1500 1575 init
    15:28:34 SIGUSR1[soft,ping-restart] received, process restarting
    15:28:34 Interface VPN06 is DOWN
    15:28:35 NOTE: the current --script-security setting may allow this configuration to call user-defined scripts
    15:28:35 TUN/TAP device VPN06 opened
    15:28:35 Listening for incoming TCP connection on Extern_IP:1201
    15:28:40 TCP connection established with Extern_IP2:50234
    15:28:40 TCPv4_SERVER link local (bound): Extern_IP:1201
    15:28:40 TCPv4_SERVER link remote: Extern_IP2:50234
    15:28:44 [Extern_IP] Peer Connection Initiated with Extern_IP2:50234
    15:28:46 Initialization Sequence Completed
    15:28:46 Interface VPN06 is UP

    I have configured –keepalive 10 60 on the client VPN ZS server parameter, but still experience the same issue. I have the same issue also between both connections. What could be wrong ?
