FortiClient Not Connecting to Windows 10: Troubleshooting Guide

Are you experiencing issues with connecting your FortiClient VPN application to a Windows 10 machine from behind your router using Ubuntu? You're not alone. Many users have reported similar problems, but there are ways to troubleshoot and potentially resolve the issue.

The problem may arise due to various reasons such as a change in the Ubuntu network stack, a router setting, or even conflicts with IP address allocation. To get started, it's essential to identify the root cause of the issue. If you're unable to connect from behind your router but devices on your local network are still visible in Nautilus when connected to a VPN, there might be a conflict between your local router and the remote router at work.

In this article, we will explore four different scenarios that may help you troubleshoot and resolve the issue:

Scenario 1: Connecting from behind my router using Ubuntu

When connecting to the remote PC from behind your router using the Ubuntu PC with openfortivpn and Remmina, ensure that you have correctly configured your VPN connection and are using the correct IP address. If this doesn't work, try restarting your network connection or checking for any firewall restrictions.

Scenario 2: Disconnecting the router and directly plugging my Ubuntu PC into my cable modem

Disconnecting your router and directly connecting your Ubuntu PC to your cable modem can help resolve any conflicts with IP address allocation. Once connected, try re-establishing a remote desktop connection using openfortivpn and Remmina.

Scenario 3: Connecting from behind my router using an Android smartphone

To test if the issue is specific to your Ubuntu setup or not, try connecting to the remote PC from behind your router using an Android smartphone with the official Forticlient VPN app and the Microsoft RD Client app. If this works without any issues, it may indicate a problem with your Ubuntu configuration.

Scenario 4: Connecting from behind my router using a Windows 10 laptop

Connect to the remote PC from behind your router using a Windows 10 laptop with the official Forticlient VPN application and built-in Windows remote desktop tool. If this works without any issues, it may indicate that the problem is specific to your Ubuntu setup.

Troubleshooting issues with FortiClient not connecting to Windows 10 can be challenging, but by trying out these four scenarios, you should be able to identify and potentially resolve the root cause of the issue. Remember to check for any firewall restrictions, restart your network connection, and ensure that your VPN configuration is correct. With a little persistence and patience, you should be able to establish a secure remote desktop connection to your office Windows 10 machine from your home PC running Ubuntu.
