The host that the port rules specify to receive the request services the request while all other hosts discard the request. Port rules are the mechanism used to direct incoming traffic on specific TCP IP ports to specific hosts or groups of hosts. All hosts in an NLB cluster must have the same number and specific port rules. Port rules can apply to a specific cluster IP address all port numbers or a specific range of port numbers and to the TCP UDP or both protocols. In addition each port rule contains a filtering mode for that filtering mode defines how the hosts in a cluster handle inbound traffic. The options for the filtering mode are as follows Disabled All traffic matching the associated cluster IP address port range and protocol will be blocked. Applications on the NLB cluster will never see this traffic. Single Host All traffic matching the associated cluster IP address port range and protocol will be handled by one specific host in an NLB cluster. For example this filtering mode could be used to direct all FTP traffic inbound to an NLB cluster to host 2 of that cluster while Web traffic is served from all nodes. Multiple Host All traffic matching the associated cluster IP address port range and protocol will be distributed to multiple hosts in the NLB cluster. When using the multiple host filtering mode you must also select an affinity. Affinity describes how multiple requests from the same client are directed among the multiple hosts. There are three affinity options None Any NLB host matching the port rule can service requests from clients. This is the most efficient affinity setting in terms of evenly distributing the workload but it should not be used with the UDP or Both protocol settings to .
