Windows 2008 Hyper-v and pfsense / ddwrt

Hi,

I have a question for the crowd.

We have a DL360 G5 laying around with an intel 1000 PT quad port network interface card, Windows 2008 standard and a requirement for 2 OpenVPN clients.
 
I have been looking into using pfsense for this task, but having some issues with the implementation, I have experience with both pfsense and untangle on dedicated machines, but the virtualization aspect has me a little stumped.

Does anyone have experience with this setup, or a suggestion for something better?

Cheers

Leon

You can start by describing the problem. "I'm having some issues with the implementation" isn't exactly descriptive.

Hi.

Sorry for the lack of description.

I have created the virtual machines, setup the NICs as external legacy adapters.
We can connect to the devices connected to the LAN interface, but cannot get out of the internal network.

The WAN and LAN interfaces both have valid IPs.
The WAN has been assigned 192.168.1.44/16 and can ping the address from the internal network.
The LAN has an IP of 192.168.10.1/16 and we cannot ping this, but can connect to the configurator.
I can see all the devices connected to the LAN connection on the network, and can connect to LAN side of the router. but there is nothing getting past the main gateway.

First of all 192.168.1.0/16 overlaps with 192.168.10.1/16

192.168.1.0/16 covers from 192.168.1.0 to 192.168.255.255

Hi infamus,

Sorry for the misleading information, I just checked, and the IPs are 192.168.1.44/24 and 192.168.10.1/24
It's getting late here, the IPs are on 255.255.255.0, not 255.255.0.0

Cheers

Did you also create two virtual networks? Connecting both VM NICs to the same virtual switch will not accomplish what you want.

Hi Cliff, thanks for the response.

Yes, I have created 2 External virtual networks for the 2 NIC ports used by pfsense.
These have been assigned to the VM as "WAN" (00:15:5D:01:28:07) and "LAN" (00:15:5D:01:28:06)

From what I am understanding now, (in the physical world), what I have essentially done is take the WAN and LAN sides of a router and plugged them directly into a layer 2 device?

So, what should the setup be?
Do I need to separate the connections into VLANs?

Cheers

Nope, shouldn't be necessary. Based on how you described network flow, the issue is not the virtualization setup, but is a configuration of traffic routing within the VM OS itself.

Hi Cliff,

Thank you very much, I am quite new at this virtualisation concept.
I understand what you are getting at, and will make the adjustments within PFSense.

Thanks again.

Cheers

Many thanks, easy to understand.

For sake of clarity.

When attempting to setup the network adapters within Hyper-V, it creates a local area connection within the parent OS.
Removing all protocols from the created connections forces the VM to use the physical adapter, and therefore creates what is called a dedicated connection within 2008R2 Hyper-V and later.

This is what was causing the issue, PFSense was seeing the network interface created by the network manager, not the physical NIC.

Cheers
