A large array of customization options for perfectly tuning your newly created Cisco-based secure tunnelĪlthough its user interface is simple and intuitive, Cisco VPN Client comes with numerous features. You can do this by registering your certificate via the PKI framework and get approval from the CA. If you're a system administrator who has already set up the client using digital certificates, you can obtain a certificate by enrolling with a Certificate Authority (CA). Moreover, the user authentication can also be established in several ways: using Remote Authentication Dial-In User Service (RADIUS), the RSA SecurID / SoftID, via the VPN device's database, or through the NT Domain (for Windows NT).
The tunneling protocols used by the client are highly secure: Internet Protocol Security (IPSec) and Internet Key Exchange (IKE). In other words, the Cisco VPN Client employs a Cisco VPN device (VPN 3000 Series Concentrators, Cisco IOS devices with Easy VPN server support and Cisco PIX Firewall Series) in order to create a tunnel (secure connection) between your computer and a VPN. Use a Cisco device to create a secure tunnel to a VPN Note that most traffic is passing over the default route, while the subnet specified in the command ( 10.10.0.0/14) is passing over the tunnel.Cisco VPN Client is a straightforward software solution that enables you to establish connections between your computer and a Virtual Private Network (VPN) using a Cisco VPN device. Your routes after this command will end up looking something like # ip routeĭefault via 10.1.1.1 dev wlp4s0 proto static metric 600ġ0.1.1.0/24 dev wlp4s0 proto kernel scope link src 10.1.1.50 metric 600ġ0.10.0.0/14 dev tun0 scope link metric 6ġ80.10.34.165 dev tun0 scope link metric 6 Where 10.10.0.0/14 should be the subnet you'd like to have pass through the VPN. Then you'd follow the instructions in this github gist.
You'd also need vpnc-script in order to make the process of setting up routes a little easier (although you can always manually go back afterwards and use the ip route commands). If you make use of an alternate client, openconnect, split tunneling is fairly straightforward. I can only address the first part of that question, "would it be possible to setup a linux VM. Barring that, would it be possible to setup a linux VM with an HTTP/S proxy and SSH that route over the VPN tunnel?
