VS2005 R2 and VPN issue

I have a wierd issue, I am running VS2005 R2 on my XP Pro laptop and it
works fine. When I VPN into my company I use the Cisco client. It is
configured for no local network access so I can only see my work
network.

When I have a VM running on my laptop and I VPN into the company, my
laptop is on my company network and I can access resources. I cannot
access anything on my local network due to the VPN client config. The
VM on the other hand cannot access anything on my company network but
can access resources on my local network.

What I would like is to have the VM access my company network when my
laptop is VPN'd into the company. Any ideas what I need to do to make
this work?

Thanks...

Mike...

Just to clarify a little terminology, there is no "guest host". The OS on
the box and on which you install VPC is the "host" computer. Each of the
virtual machines is a "guest" computer. You can only have one host, but
many guests.

Mike,

My company also uses the Cisco VPN client and local access is disabled.
The only way I've been able to access the company network via the VPN
from inside a guest host is to install the Cisco VPN client in the guest
host. Of course then, the guest host can't access any of my other guest
hosts :(...

What you want to do is actually considered a security vulnerability to the
VPN.

I have no idea whether it will work, but I doubt it -- because if it works,
it means that another non-secured machine can use your machine as "shared
access" and get access to the Company Network. That's a security breach for
the VPN Client.

You can try in NAT mode, this wouldn't be a vulnerability (in NAT mode,
the guests are basically just an application to the host)

However, the Cisco VPN client has code to detect and block VPC, so it's
moot.
