Setting up networking on Virtualbox Guest to access Host VPN

[kasunt]

Im trying to get this setup going but having quite a bit of trouble.

Host OS: Windows 8 64bit
Guest OS: CentOS 6.5 64bit

I'm using a Cisco VPN Client on my Host to connect to a number of remote servers that I'd like to access from the Guest OS as well.

Currently I have the following adapters on my Host:

Intel Ethernet Connection I217-LM - Main connection on Host (domain access/internet)
VirtualBox Host-Only Ethernet Adapter - VirtualBox adapter
Cisco Systems VPN Adapter 64-bit Windows - Used by the VPN

The intented setup on the Guest OS for me is being able to access internet & also the remote servers without loosing access to them on the Host.

How can I go about doing this on VirtualBox ??

Thanks in advance

My first thought would be to use bridged mode so that the vm looked just like another machine on the network. This will only work if your host is on a local network, preferably with a DHCP server. If your host has domain access I presume that this is the case.
