@dalias @leftpaddotpy I am not sure, why would you want to lock a process into separate namespace with a VPN. In most cases I *want* site-enabling VPN to modify *global* system configuration. I just want to choose which parts this VPN can provide, for example limiting it to only selected domains. It would be nice to have simpler ways to bind a service to just one network interface, but I don't need it often.
