Aliases/Diag_tables suddenly empty and firewall not working



  • Came in to work to find no pcs had internet access.

    Checked logs,  no obvious errors.  Checked alias status page (Diag_tables.php) and it says "no entries exist in this table".

    Rebooting has not resolved it,  nor has restoring a backup from when the router was working.
    As far as we know nothing else has been changed (hardware,  switches etc).

    Does anybody have any ideas of what i need to look at to resolve this?  I'm stumped at this point.

    Please excuse typos,  using phone to post this. Thanks
