Fortinet SSL VPN Client for Linux

After long searches I found a version of Fortinet SSL VPN Client for Linux that works well on my Ubuntu 12.04. The previous versions I found was causing the VPN connection to terminate in less than 30 seconds. This version (4.0.2254) is released in 2012 so it is pretty recent.

How do I download from an FTP server?

Latest versions of Chrome (88+) and Firefox (90+) no longer support FTP so you can use WGET or CURL to download instead. e.g.:

  1. I run into problems using Fortinet VPN Client on a recent Ubuntu machine. Fortinet rewrites /etc/resolv.conf which should be symlink pointing to /var/run/resolvconf/resolv.conf. This causes all subsequent changes of DNS settings by the Ubuntu/Gnome Network Manager not being reflected.

    The solution is to modify Fortinetclient helper/ to recover /var/run/resolvconf/resolv.conf and recover also the symlink to /var/run/resolvconf/resolv.conf.

    When Fortinet Client in terminated in a non standard way, the VPN nameservers stay in /etc/resolv.conf and delay all DNS lookups by ~5s.

    Fortinet VPN Client is simply very badly written piece of software.

    1. Hi Matěj,
      I have the same problem, but I don’t understand 100% your solution to recover the proper configurations.
      Can you help me? Explain me a little bit slower 😀


        1. Just FYI, thanks for the heads up.

          I was experiencing extreme wait times with Fortinet VPN connections.
          It got to the point where I abandoned using DNS lookups and resorted to using the IP address of the Fortinet devices.
          I believe using
          sudo dpkg-reconfigure resolvconf
          from the terminal restored my functionality.
          I also tried
          sudo /etc/init.d/dns-clean

          Not sure which one fixed me, but she's working with DNS lookups again.

  8. Forticlienvpn didn’t works anymore on Linux Mint 17 (based on Ubuntu 14.04).
    It worked well on Mint 14/15/16.

    Problem with both 4.0.2254 and 4.0.2281 is connection is created but no traffic and I didn’t see new network interface where traffic will be routed.

    Solution was to start client with sudo :

    sudo ./forticlientsslvpn

    Then ppp0 interface is created

  9. Hi, to solve this issue on ubuntu 64 bits:
    ./forticlientsslvpn: error while loading shared libraries: cannot open shared object file: No such file or directory

    do that:

    sudo apt-get install libgtk2.0-0:i386 libnss3-1d:i386 libnspr4-0d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386

    1. Thanks, but it don’t work for me . I have this message :

      ./forticlientsslvpn: error while loading shared libraries: cannot open shared object file: No such file or directory

  10. I ran into the console
    sudo ./forticlientsslvpn

    but only throws me an error message “Set Up Failed! ”

    .. I ‘m using linux mint 16 … that problems could be ? ..
    Thanks in advance.

  11. 无法在模块路径中找到主题引擎:“murrine”,
    Gtk-Message: Failed to load module “canberra-gtk-module”

  12. I could solve the problem that says “Set up failed” running the script ‘/opt/forticlient-sslvpn/64bit/helper/’ as root.

    After that, just open the VPN program again!
