Hi Ryan,<br /><br />Unless you are using Mutlicast with IGMP, then yes, I believe you will need to define static ARP entries on both routers.<br /><br />This assumes that you have NLB VIPS on both internal and external TMG interfaces...<br /><br />Cheers<br /><br />JJ

Okay so in a configuration where you have <br /><br />Internet &lt;=&gt; External Router &lt;=&gt; TMG 2010 &lt;=&gt; Internal Router &lt;=&gt; Internal Network<br /><br />Would you have to put the Multicast MAC for the External Network on the External Router and the Multicast MAC for the Internal Network on the Internal Router if they all are set to NLB with Multicast?

To find out the NLB MAC address being used on a specific network, run the following command:<br /><br />wlbs ip2mac $network_name

&gt;&gt; Robert.<br /><br />Nothing in the ISA GUI, so same as for Native NLB.<br /><br />All VIPs will use the same cluster MAC address.

How do you find out the max address of the Mulitcast VIP? In MS NLB it is easy, it is on the config screen shown in gray.

Hi Jason,<BR/><BR/>thanks for your reply. I was thinking about the same thing. Thanks for confirming. I'll give it a try tomorrow, I'm going to convert our ISA unicast array to multicast, so wish me luck :)<BR/><BR/>Regards,<BR/>Enrico

&gt;&gt;n-rico,<BR/><BR/>Thanks :)<BR/><BR/>I think the entries are only needed on the L3 devices that are closest to the NLB enabled interfaces.<BR/><BR/>More info provide here: http://www.internetworkpro.org/<BR/>wiki/Configuring_Cisco_to_work<BR/>_with_a_Windows_NLB_Cluster <BR/><BR/>This seems imply we are only concerned with the &quot;local router&quot; and talks about the NLB &quot;default

Hi,<BR/><BR/>great blog, thanks!<BR/><BR/>However I am still not quite certain as to where I should configure the static ARP entries. Are these only needed on the router/default gw that is directly behind/in-front-of the NLB cluster? Or do I also need to configure this on my Blade switches?<BR/><BR/>Best regards,<BR/>Enrico Klein
