Hello all,

I have 2 ISA 2004 Enterprise. 4 NICS: LAN, DMZ #1, DMZ #2, Heartbeat. NLB is configured on LAN, DMZ #1 and DMZ #2.

In DMZ #1, I have an F5 Big IP (load balancer with SSL Accelerator) that is load balancing a web site with a public SSL certificate on multiple IIS servers. This F5 unit is know to be incompatible with MS NLB used by the ISA 2004 Enterprise (is is not answering back to the sender's MAC address but to the source one...).

I was wondering if someone had an idea on how to bypass the NLB and use only one ISA node so I will be able to access the published web site on the F5 from the LAN.

I tryed many ways (web chaining, routing, web publishing on ISA physical IP...) but nothing worked. When NLB is enabled, it looks like there is no way arround. The goal in to make it work going through the F5. I know I could talk directly to one of my IIS servers.

Thanks for reading!

Cheers.

X.

You cannot mix a third-party load balancing product with ISA-NLB.  You have to eliminate one or the other.

Thank you for the answer!

Or maybe, I could use non-load-balanced proxy between the two... I'll give it a try one day...
