So, I followed this guide to make a namespace where I can run my VPN: https://schnouki.net/posts/2014/12/12/openvpn-for-a-single-application-on-linux/
It works fine so far, but I have one problem. I want to run a service in the namespace that opens a port I can user via browser on another PC.
So, I guess I have to forward the port that goes into my normal network to the virtual network in the namespace, but I can't figure out, how I actually do that.
Here is the output of ifconfig:
