Problem with WLBS and ASA firewall

Hi! I have an ASA 5510 firewall that we have configured in transparent (bridging) mode. We are trying to access a Microsoft Cluster through the firewall but the firewall keeps blocking the multicast mac addresses that the cluster use to access the cluster. The mac address starts with



03bf....... and the rest is the clusters ipadress in hex format. We have tried to find a way to configure the firewall to let this type of traffic trough but we have'nt found a way yet. Accessing the individual members of the cluster works fine. But then you use a unicast mac address. Any ideas?

Try configuring a static MAC address entry for the multicast MAC address

Sorry, it doen't work. When I try to configure a static multicast mac-adress I get an error message: mac-address-table static inside 03bf.xxxx.xxxx Unable to add static bridge entry.

If I try to add a "normal" unicast mac address it works OK.

Well that would indicate that it will not dynamically learn multicast MAC addresses.

I would suggest you take up this issue with your Cisco SE
