Hi

I have just set up a Windows 2008 NLB.

Clustered name is Cluster1, and there are two Windows 2008 nodes, Node1 and Node2. Both of the nodes are virtual servers residing on an HP Blade.

I have set up the NLB as per the instruction at

http://telnetport25.wordpress.com/2008/03/24/quick-tip-configuring-network-load-balancing-nlb-on-windows-2008-for-exchange-cas-servers/

However, the clustered IP/name cannot be reached (via Ping, RDP etc) from outside the subnet that it resides in (Cluster1, Node1 and Node2 all reside in the same subnet).

Any ideas on how to fix this?

Cheers

Can you reach the subnet at all from outside the subnet or is it just those machines?  Did you check your ARP tables on your router to make sure it's moving traffic to the right network segment?

Hi

Yep, have no problem reaching that subnet (192.168.1.0/24) from outside the subnet. My laptop is outside the subnet and I can ping Node1 (192.168.1.1) and Node2 (192.168.1.2) ...but, for some reason, I can only ping Cluster1 (192.168.1.3) from any machine in 192.168.1.0/24.
