[Solved] Linux FortiClient can't connect into company network

mivl · ‎08-01-2018

First of all - let me apologise for creating such a "common" thread here on the forum. I had no other choice but to ask here for help due to my issues with the connection to our company network using FortiClient SSLVPN.

1. The problem:

My employer has his VPN connection probably by FortiGate - for that, I have been using this application provided for Linux (http://www.fortigate.cz/u...n-linux-442270tar.gz). It's been working more less fine for more than a year, but last Wednesday I started experiencing issues with the connection.

When I click on the "Connect" button, the application is starting the connection sequence as usual and a pop-up window is showing usual output (... -> Connecting -> ... -> Tunnel running). At this point, I should be connected to the network and everything should be fine, but when I try to access any company's server, it is unreachable. I suspect the issues might be with the network configuration because when I try the same thing but using the Android client app, everything is just working fine.

2. System specification:

OS: Linux Mint 19 "tara" (based on Ubuntu 18.04)

I have "forticlientsslvpn_linux_4.4_2336.tar.gz"

If you have Dropbox/FTP i can upload it so you can test.

Have a look at the routing table when you connect (netstat -r). Do you see any routes for 10.126.0.X pointing to the ppp0 interface?

mivl · ‎08-06-2018

I think the problem is not probably caused by the client - since I've been using the same client for more than a year. I see the problem rather somewhere around the network configuration but thank you for your offer though!

Thank you for your reply. Tried ssh connection to the 10.126.0.126

netstat output during ssh connection attempt:

no route pointing to the ppp0; most of them are just docker networks.

edit: sorry for wrong posts nesting in this thread. I am new here and still trying to figure this out. :)

Just solved the problem myself. Since I became so frustrated about the whole situation I end up downloading a non-official client for that. This works perfectly fine [link]https://hadler.me/linux/openfortigui/[/link] and works even better than the official client. The openfortigui client is open source, so it shouldn't be any security risk (look into the source code). Hopefully, this will help anyone facing any similar problem.

On a side note: I am really disappointed with the official Linux Client support.
