This software allows you to connect to an F5 Networks VPN server (BIG-IP APM) without using their proprietary VPN client.
It is not supported or affiliated with F5 in any way. I actually find it rather sad the client they provide is so terribly poor that I had to write this in order to get reliable access to my company's VPN.
This software does not require any software from F5 to be installed on the client. The only requirement is Python 3. It works on at least Linux and MacOS systems, but porting to any similar OS should be trivial. Porting to Windows, on the other hand, is probably not reasonably possible.
The script requires ppp. If you are on Linux, install it using your package manager. If you are on MacOS, you already have it.
The script also requires netstat, which is generally packaged as net-tools.
sudo ./f5vpn-login.py --sessionid=0123456789abcdef0123456789abcdef your.fully.qualified.hostnameYou can find the session ID by going to the VPN host in a web browser, logging in, and running this JavaScript in Developer Tools:
document.cookie.match(/MRHSession=(.*?); /)[1]If your organization does not use 2FA and you are able to log in with just your username and password:
sudo ./f5vpn-login.py user@host-
By default, the script will change your DNS servers to the ones provided by the VPN server. Skip this step by by passing the
--skip-dnsoption. -
By default, once connected, the script will route all traffic through the newly-created VPN network interface. Skip this step by passing the
--skip-routesoption (your VPN connection will be useless if this option is used, so only use it if you plan to set up the routing table yourself).
user@host is saved for future invocations, so doesn't need to be specified on future invocations.
Use CTRL-C to exit.
The application will save "user@host" and last session ID in ~/.f5vpn-login.conf. In case of problems or for reset the session data simply remove that file.
