    Hi @Fabio

    The log that you provided to us:

    [ 2018/08/19 11:43:27 ][SecuExtender Agent][DETAIL]  Secure session negotiation begin
    [ 2018/08/19 11:43:37 ][SecuExtender Agent][ERROR]   timeout (0x0)
    [ 2018/08/19 11:43:37 ][SecuExtender Agent][ERROR]   Failed to create security tunnel (0x0)

     

    According this log is coming from the SSL VPN process without response. So leads VPN tunnel is unable establishing successfully.

    Does this symptom still exist after reboot this device?

    It seems it does not work, i try several time but with the same result.
    what i notice tht access Zywall on the public address is very slow ( it is connected to 1GB line) 
    when everything works the access of console was  very fast as it must be.

    Hi Fabio 

    As our discussion by private message.

    The reason of this issue is because you are using admin type user to login to SSL VPN.

    But admin type user is not allowed in SSL VPN.
