Level.4 app for iPhone and iPad

Level.4 is a network proxy client that designed for protecting your Internet traffic against network-attack (DNS hijacking, leak, sniffing, inspection, spoofing...). And, it may require you some professional knowledge to use.

Features:
1. Self-defined network protocol
2. Self-implementation TCP/IPv4 stack
3. Customizable port number
4. Customizable DNS servers (GoogleDNS is the the default DNS Server)
5. Connecting to server automatically when iOS device wakes up

To use Level.4, you should install Node.js v4+ and LightSword on your server.

Installing LightSword:

> [sudo] apt-get update -y
> [sudo] apt-get install curl -y

> [sudo] curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
> [sudo] apt-get install -y nodejs
> [sudo] npm install lightsword -g

> [sudo] apt-get update -y
> [sudo] apt-get install curl -y

> [sudo] curl -sL https://deb.nodesource.com/setup_5.x | bash -
> [sudo] apt-get install -y nodejs
> [sudo] npm install lightsword -g

> [sudo] yum update -y
> [sudo] yum install curl -y

> [sudo] curl -sL https://rpm.nodesource.com/setup_5.x | bash -
> [sudo] yum install nodejs -y
> [sudo] npm install lightsword -g

Ok, lets run LightSword:

> lsserver --port 8081 --password mylevel4 --fork --cluster

Now, run Level.4 on your iOS device, then tap Add Server Configuration, fill in your servers information: label (eg. My Tunnel), address (IPv4, IPv6 or domain name), port number (8081), password (mylevel4), and save it.

Finally, switch on connection toggle, Level.4 is going to protect your network traffic.
