Windows After a few relatively small changes and not-so-earth-shattering features, the Windows 8 blog has now unveiled something many of you will surely appreciate: Hyper-V, Microsoft's hypervisor-based virtualisation software, will be integrated into the client releases of Windows 8 - not just the server releases.

RE[2]: Partly off-topic question

Is there a problem on Windows to run multiple VPNs simultaneously?

At work I use three VPN clients on a daily basis for connecting to our customers' sites; Checkpoint, Nortel and Cisco.

Only the one from Checkpoint lets me use the local network while connected to the VPN.

Whether Windows' built-in IPsec must be enabled or disabled varies between the clients, so you have to know when to start/stop the service.

For these reasons I have three VM images dedicated to each of the VPN clients. My host is currently OS X, but I moved the VPNs into VMs one or two years before switching to a Mac.

I have never been able to connect to two of the VPNs simultaneously. IIRC, you can even experience clients that are incompatible to the point where you can't have both installed at the same time.

At the low end of the annoyance spectrum is the issue with existing TCP connections breaking when dialing a VPN. (Somebody calls you on VoIP, you need to connect to a VPN to answer their question, and bam! Call ended.)

On my Linux box at home, I am able to connect to the Cisco VPN server without loosing control the way I do with the Windows client. Normally vpnc does the usual routing table hijacking, but if I configure it to not run the default connect script, all it does is create a tunneling device. I can then route specific destination addesses through the VPN however I want.

I don't think the issue is primarily with Windows, but rather with the VPN clients that mess too much with my system's routing table. I have however not found any open source client for the Nortel and Checkpoint VPNs. I have not attemted to use non-official clients on Windows. The easy solution was to virtualize XP on XP to work around all the pain.
