NordVPN: High-level VPN service
OpenWRT: OpenWrt is a highly extensible GNU/Linux distribution for embedded devices (typically wireless routers). Unlike many other distributions for these routers, OpenWrt is built from the ground up to be a full-featured, easily modifiable operating system for your router. In practice, this means that you can have all the features you need with none of the bloat, powered by a Linux kernel that's more recent than most other distributions.
Based on: https://nordvpn.com/tutorials/openwrt/openvpn/
You need to install OpenWRT packages only once
opkg update
opkg install openvpn-openssl
opkg install ip-full
opkg install luci-app-openvpn
Since I'm currently using a very slow and unstable 3g internet provider, I don't keep the vpn on all the time, hence I made an optimized Watchdog that will check and restore the vpn only after its first use since last boot. I just keep the openvpn service disable so that it will be started only by demand. I also doesn't keep aria2 or transmission services running all the time in hope to save some electricity.
The script also works perfectly if you have the openvpn service enabled in order to keep you vpn lasting.
