Sometimes you just need to stop and listen.

This challenge is an introduction to our network exploit challenges, which are hosted over OpenVPN.

Instructions:

Install OpenVPN. Make sure to install the TAP driver.
    Debian (Ubuntu/Kali) linux CLI: apt install openvpn
    Windows GUI installer
Obtain your OpenVPN configuration in the challenge modal.
    You will obtain a separate config for each challenge containing connection info and certificates for authentication.
Launch OpenVPN:
    CLI: sudo openvpn --config ${challenge}.ovpn
    Windows GUI: Place the config file in %HOMEPATH%\OpenVPN\config and right-click the VPN icon on the status bar, then select the config for this challenge

The virtual tap0 interface will be assigned the IP address 172.30.0.14/28 by default. If multiple team members connect you will need to choose a unique IP for both.

The standard subnet is 172.30.0.0/28, so give that a scan ;)
