Question

SSL-VPN connects and disconnects straight away

Hi All,

 

I have an SSL-VPN that did work, however now, users connect and straight away disconnect. I have ran a debug and obtained the following (full debug attached)

 

[4832:root:31266]tunnel_state.c:1278 no more addresses available

 

To me this suggests that the IP range for the SSL VPN is full? Currently though I do not have any users on the VPN, is there a way we can clear this?

 

Thanks

    Although I don't see your attachment, my guess is about the same as yours for the log. Then I'm wondering what happened between the time "did work" and "now". Did you upgrade the system or change some SSL-VPN related config, or really nothing has happened?

    I had that same issue awhile back in v5.2.3 iirc and it didn't make any sense to me. What I did was to kill the  sslvpn process

     

     

    Execute a kill against the proc-id

     

    1st run a new diag debug 

     

    diag debug application  sslvpn -1

     

    2nd

     

    fnsysctl cat /var/run/sslvpnd.pid

    fnsysctl kill -9 <pid from above>

     

    rerun and make sure a new pid comes up

     

    3rd

    fnsysctl cat /var/run/sslvpnd.pid

     

     

    review any diagnostic output ;

    if a multi-vdom environment

        fnsysctl killall sslvpnd

    then

        diag sys top-summary "-i 10"

    would be handy.

    And, that's what TAC would ask you to do or do it themselves when you open a ticket and don't find anything wrong in the config. It just affects to any ongoing SSL VPN sessions if anything is up, instead of affecting to everybody when you reboot the unit.
