SSL VPN does not connect after upgrade to SFOS 18.0.3 MR-3

We upgraded one of our Firewalls to SFOS 18.0.3 MR-3 from 18.0.1 MR1 and our SSL VPN clients quit working.

We get the error:

the system tried to join a drive to a directory on a joined drive

Any thoughts on the cause?

  • Hello April,

    Thank you for contacting the Sophos Community!

    Please check if you don't have any DNAT rule with the service set as ANY.

    If you don't have any DNAT rule with service set as ANY, please share the logs from one of the clients and the /log/sslvpn.log

    Regards,

  • To thicken the plot, I had rolled the firewall back, with COVID remote work we cannot afford to have the VPN broken.

    I got in after hours, created a test user and tested it on the old firmware, it worked, upgraded again and tested the test user I just created and it worked. Had a User test it, it worked.

    To summarize I rolled it back, waited a few weeks installed the firmware again and it worked.

    Not sure I am ready to test it on our HA cluster with 300 VPN users.

    Any thoughts as to why this worked?
