Why does the network fail on my computer when I add a VPN route?

Question

macOS

L2TP access is configured in the office. When you connect home on Mac OS, a route is automatically added. After that, on the home computer, some sites stop responding the first time, most often pages open after updating. What could be the problem?

Configuration/Screenshots

Для автоматического добавления маршрута на Mac OS было проделано это:
sudo touch /etc/ppp/ip-up
sudo chmod +x /etc/ppp/ip-up
sudo nano /etc/ppp/ip-up
#!/bin/sh
/sbin/route add -net 192.168.1.0/24 192.168.99.1
до добавления маршрутов. подключен wifi и ethernet

после подключения и автоматического добавления маршрутов

В офисе Mikrotik RB750GR3. Проблем с доступом туда нет, только с интернетом.
Дома Mikrotik Hap AC2. На нём аналогично настроен L2TP, с работы из windows подобных проблем не наблюдалось.

Most likely, when raising vpn, all your traffic starts going through the office, and in the office someone did not correctly configure routing or dns. It is better to refuse the default route when raising vpn, create a cmd file with routes on the desktop and run it after raising vpn. Then you will go to the Internet through the Home router.
