I've moved to a new company and I need to use an L2TP VPN with my M3 Air / Sonoma 14.5 to connect to a remote machine.

I was able to get the VPN working quite easily (had to do set some additional routes) and I was able to connect via Remote Desktop to my Windows working machine the whole day. Around the end of the work day my VPN dropped and has stopped working ever since.

It connects, but I don't really have any internet and after 2-3 mins I get disconnected from the VPN. I was using the 5Ghz Wi-Fi router at home the whole day. The weird thing is that right now the VPN is working via Personal Hotspot and does NOT drop (tested for 20-30 mins). I tried reseting my router to factory settings. I'm using a Static IP

Here are the last logs from ppp.log
