Default Handling of Client Requests

Network Load Balancing is designed so that network traffic is not affected for the virtual IP address(es) of applications that are not being load-balanced. All traffic not explicitly load-balanced with port rules is sent to the default host. For example, incoming Telnet requests for the Virtual IP addresses are handled by the default host.

Therefore, if you do not want to load-balance some traffic for the virtual IP address, you do not define a port rule for it; the default host then handles all the traffic for that address. However, the default port range (0-65535) covers all ports, so you need to make sure that the port range for any port rules you define does not include ports associated with applications whose client requests you do not want to load-balance.

Undesired load-balancing is not an issue for dedicated IP addresses. Incoming network traffic for the dedicated IP address on each host is never affected by Network Load Balancing.
