Security Fabric Telemetry Compliance Enforcement Tunnel Mode SSL VPN IPv4 and IPv6 2-Factor Authentication Web Filtering Central Management (via FortiGate and FortiClient EMS). FortiClient WAN optimization over IPsec VPN configuration example This example shows how to add WAN optimization to a FortiClient IPsec VPN. The IPsec VPN tunnel allows remote FortiClient users to connect to the internal network behind the FortiGate unit. The vulnerability affects FortiClient 5.6.0 and earlier for Windows and Mac, and version 4.4.2334 and earlier of the SSL VPN client for Linux – the Android and iOS apps are not impacted. Patches are included in FortiClient 5.6.1 for Windows and Mac, and FortiClient 4.4.2335 for Linux, which the vendor released alongside FortiOS 5.4.7.

The forticlient VPN software is borked, when using split horizon, since OSX El Capitan. The problem is that DNS requests are sent out on the normal primary interface to the DNS of the VPN tunnel.
How do we get the DNS requests to be sent out over the correct interface (i.e. VPN tunnel)

(Re)improved on just about everybody else's improved answer (@elmart, @user26312,myself). Edits should not be needed in the script:
Make the file you put this in, executable and execute (after connecting with the VPN) with sudo. Before the script does any changes, it looks at your current default route and therefore knows your current gateway and interface.
Not a complete solution, you'll have to do the following two high-level things after each VPN connection setup:
- We'll have to set the tunnel's interface to
ppp0
- Redo default routes (because 1. implicitly sets the wrong default gateway, split tunnel should still work correctly hereafter)
Create a file with the name
scutil-forti
for exampleRedo gateway routes, so make another file,
routes-forti
, with (mind the lines with specific settings for your network): now, execute,

I've reworked @hbogert's solution into a more manageable single script:
That is assuming you're using en0 interface and 192.168.1.1 default gateway.If not, replace those with your corresponding values. If you don't know them, type
route get www.google.com
to get them.Then:- Place that into a file (e.g. 'fix-vpn') somewhere in your path.
- Give it execute permissions (
chmod u+x fix-vpn
). - Run it with sudo (
sudo fix-vpn
) just after connecting to vpn.
I've tried it and it works.As I said, this is just a rework of a previous solution. I just posted it as a separate answer because I didn't have space enough in a comment.

BTW, I also thought this could be included in a
/etc/ppp/ip-up
script so that it gets automatically executed when connecting. But for some reason, it doesn't work that way. If somebody can explain/improve on that, please do.elmartelmart
I was able to use an older version of Forticlient and confirmed that it works!
Here's the link to it on my dropbox:

Vmware view client for mac pcoip. UPDATE: Downloading and installing the newest and official version 5.4.1 for Mac OS X fixes all the problems on Mac OS X El Capitan.
As described in the fortinet forum one should download the newest (yet unpublished) version of the FortiClient to fix the problems on Mac OS X El Capitan:
This was the easiest solution for me.

Improving on @elmart's answer a little bit (I think).
That way the script doesn't need to be edited (and changing interfaces shouldn't be a problem).
xargs
is used to strip the whitespace.I've also added (though I don't know if this is an improvement):
To the very beginning of the script to remind people to use sudo.

I took hbogert's script and wrapped it in Applescript for myself and another employee, it's available here:https://www.dropbox.com/s/lh0hsqdesk3i0n7/Execute-Post-VPN-Connection.app.zip?dl=0
Simply connect to VPN, then execute the app and type in your admin password (required for sudo). NOTE: MUST BE SAVED IN /Applications/

I solved the problem for me by re-configuring the DNS settings to use Google DNS servers before the ones provided by FortiClient. Unfortunately, this has to be done after each re-connect.

On my current OS X version (Sierra 10.12.6) & FortiClient 5.6.1 it seems like if ServerAddresses has more than 2 addresses, then the 'set' call doesn't persist anything (if you 'get', nothing will have been updated). To workaround this, I decided to only keep first FortiClient DNS address and merge it with my public DNS address (8.8.8.8).
Moreover, I would suggest to automatically run the bash script on FortiClient connect : this can be done by exporting FortiClient configuration script then re-importing it
Full guide below :
Fortinet Client For Mac Vpn Software
1/ Create following bash script and store it somewhere (in my case, it was into
~/bashscripts/update-forticlient-dns.sh
) and don't forget to replace the <FIRST IP ADDRESS FOR FORTICLIENT DNS>
by the result of scutil --dns | grep 'nameserver[0]'
while your FortiClient connection is up2/ Run FortiClient, then go into Preferences >General and click the Backup button which will export your FortiClient configuration into a file
3/ In this file, locate & edit the /forticlient_configuration/vpn/sslvpn/connections/connection[name='YOUR CONNECTION']/on_connect/script/script node and call your script inside it :
