VB won't bind to IPSec Virtual Adapter

Edit:   Edit:   Edit:

Hi,
I have VB 4.3.12 installed on a Dell Laptop. The laptop is used to remote access to a corporate net. For reasons unknown, I can't get a CentOS 7 guest to bind to the Cisco Virtual Adapter created by the VPN client. The systems are that it won't obtain an IP address. I've tried using all the different network modes. NAT Bridged is the only network configuration which is able to detect the virtual adapter...but still the guest will not bind and obtain an IP.

What exactly do you mean by "NAT bridged"? NAT and bridged are quite different networking modes.

I would not expect any network mode to do what you want. VPN connections are quite different from a normal network connection and are quite difficult to share.

Hi Bill....It was my observation that NAT Bridged was the only network setting which enumerated the Cisco VPN adapter. The bigger issue is getting it to work. I'm hoping someone may have experience with this mode of operation.

I've made some progress....I managed to get the VB guest to bind to the adapter of the laptop. The guest host has an RFC address 10.0.2.x as it should. Now about how to get the packets to route through the IPsec Adapter.

If you have a 10.0.2 IP you are using NAT. The guest will be sharing the host's connection - that is how NAT works. If it is going to work (which I doubt), you don't need to do anything.
