ip netns add vpn. Creates a network namespace and names it vpn. ip netns exec vpn ip link set lo up. Bring up the loopback interface in the vpn network namespace. I am running openvpn client in a namespace. I am starting it as: ip netns exec vpn openvpn --fast-io --config /etc/openvpn/OpenVPN-Configs/Random-TCP.ovpn Jan 29, 2017 · #! /bin/bash up {# create network namespace ip netns add vpn || true # bring up loop device ip netns exec vpn ip link set dev lo up # move VPN tunnel to netns ip link set dev " $1 " up netns vpn mtu " $2 " # configure tunnel in netns ip netns exec vpn ip addr add dev " $1 " \ " $4 / ${ifconfig_netmask:-30} " \ ${ifconfig_broadcast:+broadcast ip netns monitor ip netns list-id [ target-nsid POSITIVE-INT] [ nsid POSITIVE-INT] DESCRIPTION A network namespace is logically another copy of the network stack, with its own routes, firewall rules, and network devices. By default a process inherits its network namespace from its parent. # ip -n container addr add 192.168.4.33/32 dev wg0 # ip netns exec container wg setconf wg0 /etc/wireguard/wg0.conf # ip -n container link set wg0 up # ip -n container route add default dev wg0 And voila, now the only way of accessing any network resources for "container" will be via the WireGuard interface.

I tried a few things but this is way over my head: ip link set dev "$1" up netns vpn mtu "$2" Any help fixing this command would be greatly appreciated. – zilexa

The plan is to create a network namespace, connect to a VPN within that namespace, and then start various applications within that namespace that are currently blocked by my UK based ISP. I found a walkthrough that works fine if I run the script manually, but when I try and automate it with an upstart script it fails to work.

For programs inside the namespace, the only network connection to the outside world is through the VPN tunnel. This prevents VPN leaks. Multiple VPN connections can be opened at the same time each in its separate namespace. Scripts openvpn-netns. Start OpenVPN connection in namespace. Must be started as root. Usage: sudo openvpn-netns
