Watchblob - Connect to 2-factor WatchGuard VPNs with OpenVPN

This tiny helper tool makes it possible to use WatchGuard / Firebox / <> VPNs that use multi-factor authentication with OpenVPN. It supports the Watchguard Authpoint App or SMS as multi-factor.

Rather than using OpenVPN's built-in dynamic challenge/response protocol, WatchGuard has opted for a separate implementation negotiating credentials outside of the OpenVPN protocol, which makes it impossible to start those connections solely by using the openvpn CLI and configuration files.

What this application does has been reverse-engineered from the "WatchGuard Mobile VPN with SSL" application on OS X.

Tazjin published a blog post describing the process and what is actually going on in this protocol.

Installation

Make sure you have Go installed and GOPATH configured, then simply:

go install github.com/cgroschupp/watchblob@main

Usage

Right now the usage is very simple. Make sure you have the correct OpenVPN client config ready (this is normally supplied by the WatchGuard UI) simply run:

watchblob --host vpnserver.somedomain.org --username username --password p4ssw0rd
NAME:
   watchblob - 2-factor WatchGuard VPNs with OpenVPN

USAGE:
   watchblob [global options] command [command options] [arguments...]

COMMANDS:
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --username value  Username
   --password value  Password
   --password-stdin  take the password from stdin (default: false)
   --token value     token that is used to answer the challenge
   --host value      Watchguard fqdn
   --debug           enable debug output (default: false)
   --insecure        allow insecure ssl connection to watchguard (default: false)
   --help, -h        show help

The server responds with a challenge which is displayed to the user, wait until you receive the SMS code or whatever and enter it. watchblob then completes the credential negotiation and you may proceed to log in with OpenVPN using your username and the OTP token (not your password) as credentials.
