Linux VPN clients

Does anyone have suggestions for Linux based VPN client software to users into a Palo Alto Managed environment.  The dynamics (frequent upgrades of various distributions) is causing issues with our current 3rd party commercial VPN solution.  Any suggestions would be greatly appreciated.  Clients are Ubuntu based laptops.

With PAN OS 5.0, VPNC can be used as the VPN client on Ubuntu.

Please refer to for more details.

You can try ShrewSoft VPN client. The standard client is free to use (personal & commercial). We use it on Windows and it works great with our OTP 2-factor authentication as well, except for an IPSEC SA/IKE rekey issue that causes the connection to drop just about every hour; we have the same issue with the native OS X & iOS clients too though.

I have used VPNC integrated into NetworkManager (the default on my Linux distro, OpenSUSE) and it worked great... make sure X-Auth is turned on and you should be good to go.

I would firstly try VPNC or perhaps OpenVPN.

Alternatively if those said ubuntu laptops could be put behind a pfsense firewall you could get that to do all the VPN for you.

Thanks Guys.  We will pursue the VPNC  option.  I appreciate your feedback.
