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 with03bf....... 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?
