Host Vista x64 using guest XP Cisco VPN

nutcracker · Post by **nutcracker** » 24. Dec 2008, 05:00

I have a guest XP running on my host Vista x64. I installed our cisco client software (4.01) in guest XP and it connects just fine. I would like to share the VPN with the host vista x64, but can't figure out how. Cisco claims it will not support Vista x64 and IPSec, so this seems like my only option.

The VPN uses transparent tunneling, IPSec over UDP (NAT/PAT).

I'm rather lost at how to proceed. I've modified the XP guest settings from NAT to HOST Interface. The VPN in XP works with either setting, but vista cannot connect to the VPN. In Vista, nothing seems to show up in Network Connections that would let me bridge my Local Area Connection.

Correct me if I'm wrong.

I also tried to replicate your situation on my end, and I don't believe you can because the NAT acts as a piggy back OS using the Host's ip address. So you can't modify the Host ip address from the guest. And the Host Interface just makes it as if your guest OS is a different computer on a network. It acts like 2 computers and their network IPs will be different.
I think the only way is to put the VPN on the Host.

Why do you need to put it on the Host? You can do almost anything on the guest OS to tunnel.

Switching to HOST networking you add host to your local network topology. As I understand Cisco VPN client allows you to connect to local network from secured environment but not in opposite direction.

I'm not sure I follow. The VPN software does not work on the host. I could care less about how I configure the guest, I just want to make the VPN accessible from the host via the guest.

How do I tunnel my host thru the guest?

I know it can be done, just not sure it can be done with VirtualBox. We had a developer at our company that ran XP in a VM with a host Vista x64. He was successful at connecting to the VPN in Vista x64 thru the guest XP OS. But I'm not sure what VM he was using, might have been VMWare.

Maybe I wasn't clear, but I don't care how the guest XP is configured (whether host or NAT). I'm just trying to figure out a solution that works. If it's even possible with VirtualBox. If it's not possible, then I'll try another VM solution.

If you want to be able to use your VPN from the Guest in the Host, you need to mess around with routing and routing tables. There is enough info on the internet on this subject. Please see that, we aren't specialized in that. Your VPN works on the Guest, that is as far as we can help you.

Its as simple as using HIF and adding a route that changes the gateway like:
route add IPRANGE_OF_VPN_DESTINATION mask 255.255.255.255 IPADDRESS_OF_VPN_GATEWAY metric 5

I've done this with VMware Player a lot.

Host OS: Vista x64
Guest OS: XP 32-bit

I'd connect the Guest OS with Cisco VPN.

I then used the "route add" command to route the network IP through the VMware Network device added in the Host OS.

Sun VirtualBox does NOT add any network connections to the Host though, so I don't know how to make it work with VirtualBox.

Hi,

I´m having the same problem... as you probably know, AT&T Network client is not available on MAC Os.

I want to take advantage of my linux guest... which support AT&T client...

Any thoughts?

Regards.-

I got VPN working with it now. It's actually a LOT easier with VirtualBox and VirtualPC than it was with VMware.

I have Windows XP installed as the Guest OS.

When you install VPN software like Cisco VPN or SonicWall, it adds it's own network connection to the system.

Tell Windows to "share" that connection.

Then, for the guest's default "Local Area Connection", give that a static IP of your choosing.

Now, in the Host OS, use the "route add" command to route the IP ranges of the network you wish to connect to with VPN to the static IP of the guest OS.

I use Vista Ultimate x64, and then with both VirtualBox and VirtualPC, I've used different VPN apps to connect with the guest, and then I route my host's traffic to the guest OS.

It's a lot easier to set up compared to the horrific VMware guides I've seen.

I don't know when I'll get them finished, but I was planning on having guides/screenshots there.
