vpn – route not changing anymore since upgrade to big sur

Since I have upgraded to Big Sur my VPN post script has not been firing.

I have a simple script setup in /etc/ppp/ip-up that allows me to access things outside of the network while still accessing things in the internal network. It has been working for a while now and ever since upgrading to Big Sur I have to run the command manually to be able to access external websites/services.

did something major change with how they handle this file? it set to be executable and everything so I don’t know what the problem is, below is what that file looks like.

#!/bin/sh

/sbin/route change default 192.168.1.1

if I run that command in the terminal it works so I’m curious if Apple broke something or changed how it works.
