Client Split tunnel VPN not working after reboot MacOS

[RichardChen1]

We have a vmx100 in Azure - which remote user vpn into.

We followed this guide and add static route on MacOS for the split tunnel to work.

route add -net <destination subnet> -netmask <subnet mask> -interface ppp0

https://documentation.meraki.com/MX/Client_VPN/Configuring_Split_Tunnel_Client_VPN#Configuring_Split...

It works fine on most of the Mac and Windows users.

However, the static route disappeared after os reboot.

We used the os admin user to add the route.

Any idea how to fix that?

Not working OS version: Sierra 10.12.6

Working version: High Sierra V10.13.6

For Windows users use this system.

Thank you for the link.

Windows users are fine.

Issue is with MacOS.

It seems that on MACos using that command adds non-persistent routes.

That means they are flushed at reboot.

Our Mac guru has found a workaround by adding a script that runs everytime the VPN is connected.
