This looks like Cisco IPSEC-based VPN. vpnc supports this, so you may want to try installing 'vpngui' or vpnc-gui.

Our Cisco IPSEC VPN uses two-factor cert+password auth, which AFAIK still doesn't work on vpnc, so I haven't tried either of these packages. We keep an OpenVPN up as well, since Cisco's official VPN client sucks on Linux (kernel module panics on SMP kernels, which is almost any client these days), so I use the openvpn client myself.
