Already asked a similar question, but the answer is not exactly that, so a few modifications of it. In which file you need to add routes, so that when the PC is restarted / on-off, they, routes, will remain and be loaded automatically. i.e. to be defaulted?
System CentOS 6, connecting to the network via VPN. When I enter it through the terminal, everything works, I don’t have any complaints, but I’m fed up with constantly introducing these routes, as this causes some inconvenience.
