Accessing a website over L2TP using OrangePi as a middle man?

Android 13 no longer supports L2TP. I need to access my work website over L2TP. The only solution I could came up with so far is to use a single board computer as the middle man to handle L2TP traffic and pass it to my phone. But I don’t have a technical solution. My SBC is an OrangePi PC with Ubuntu Linux on board so it supports L2TP. I can connect the Pi to my phone’s hotspot over Wi-Fi. I can ssh to the Pi from my phone. But how to set up the Pi as a server or maybe do some routing/forwarding to access my work website from my phone’s browser?
