I have implemented IPsec with SAML on a fortigate and can connect fine to it from some machines but other machines are incredibly unstable. The forticlient (vpn only 7.4.3) will connect, the application will be unresponsive for a few seconds and then will say connected however no packets will flow.
What is the best version of FortiClient to use with IPsec/SAML for stability? Also is there a way to download older versions?
Hi
FortiClient version 7.4.3 includes a known issue that appears to align with your situation, listed under BUG ID 1102421. You can find more details in the official release notes at the link below:
https://docs.fortinet.com/document/forticlient/7.4.3/windows-release-notes/573433/new-known-issues
Similar issues have been reported under BUG ID 1051036 and 1089023 in both FortiClient versions 7.2.8, 7.2.7, and 7.2.6. I believe this could be contributing to the problem you’re currently experiencing.
Based on my research, I haven’t found any known issues in FortiClient version 7.2.9 that appear to match your current situation. However, it's important to note that this doesn’t guarantee the absence of issues—some problems that are visible in version 7.4.3 may still manifest differently or remain undocumented in version 7.2.9.

While Fortinet hosts different versions on the public site and this procedure requires a valid support account.
