Cisco Secure ACS and Windows NLB

Unanswered Question

I have two ACS servers and have been trying unsuccessfully to setup Windows NLB for them. I can successful setup the NLB but ACS won't respond on the clustered IP. Other services running on the clustered IP will respond so I believe the NLB is working correctly.

Has anyone had any success with ACS and Microsoft NLB? I can?t find any documentation to suggest that they are incompatible but I think this may be the case.

ACS is not tested with NLB but if cluster hosts are attempting to communicate with the ACS using their clustered IP then ACS should reply.

Do you see any hits on acs ? If you sniff the acs interface, what is the source IP address ? Is it clustered ip or clustered host IP ??

Also on acs --->Network configuration add aaa client with host IP and clustered ip . Now see if acs responds to NLB.
