For more information, see network settings in debian-Debian for the Linux release. A debian system computer in our department is configured with a public network address: 202.96.x.x; to allow customers to connect to this computer from the public network. You can use ifconfig to view the tun0 device after each restart and cannot access the Internet. Use the command/etc/init. d/openvpn stop to disable tun0 and then access the internet. After each restart, you must manually disable tuno to access the Internet. How can I set it to automatically disable it when it starts. (Run the sysv-rc-conf command without the vpn service ).
Please give me some comments. Thank you !!
