Hi All,

I got 2 box loaded with WIndows 2008 64bits data center with Hyper-V enabled. Each box is connected to 2 different ISP as the public access.

Box 1

-------

I have setup 3 Hyper-V with WIndows 2008 64bits Data center with NLB enabled.

Hyper-V 1
- NIC 1 - Connected to the public interface of the Host Machine and have public IP added
- NIC 2 - Configured with private IP ( 192.168.0.231 )
- NIC 3 - Configured with private IP ( 192.168.0.232 )
Hyper-V 2

------------
NIC 1 - Connected with private IP ( 192.168.0.233 )

NIC 2 - Connected with private IP ( 192.168.0.234 )

Hyper-V 3

------------

NIC 1 - Connected with private IP ( 192.168.0.235 )

NIC 2 - Connected with private IP ( 192.168.0.236 )

I have then setup the NLB cluster as follow:

Cluster IP 192.168.0.220

Host Member - Hyper-V 2 NIC 1

Host Member - Hyper-V 1 NIC 1

The cluster setup successfully and the interface converged successfully for both Hyper-V and I can ping to the cluster IP 192.168.0.220. However, I was having problems to setup the port rules for the mail services ( 192.168.0.233 and 192.168.0.235 ).

Cluster IP address : All

Start : 25 End : 25

Protocol : Both

Mode : multiple

Priority : -

Load : -

Affinity : -

I can see the port rules status is enabled in the NLB Manager. But when I try telnetting to the cluster IP 192.168.0.220 at the Hyper-V 1 command prompt, I am getting the port connection failed. Local telnet at 192.168.0.233 and 192.168.0.235 has SMTP opened. Any idea where am I missing?

One thing I notice at Hyper-V server for the 3 NIC, the NLB is not enabled 'checked' , does this has anything to do with it?

thanks for your time
