FortiGate split-tunneling-routing-negate enable not working with Unix Client

[ChristianK]

Hello,

we using the FortiClient on Windows and Unix.

On our FortiGate 6.4.5 we use

 config vpn ssl web portal
    edit "EB-SSL-VPN-Test"
       set split-tunneling-routing-negate enable
       set split-tunneling-routing-address "MS-Teams"

This is working with the Windows Client

On the Unix Client, the routes aren't implemented correctly.

Is this known?

Is there a solution available?
