Open New Entry When Source Port Different – When enabled, each session a client opens is recorded in the client table and is balanced separately. This provides more accurate minimum-user load balancing. When disabled, all of the client's sessions are considered a single session, providing better performance.

Select New Server When Source Port Different – When enabled, different sessions opened by a client's application will be served by different servers, according to the load balancing algorithms. This option enhances load-balancing performance but may hinder some applications that depend on being served by the same server. It also may overload the WSD's internal tables. This option overrides the New Entry On Source Port option.

Load Report Interval– The interval (in seconds) for sending dynamic updates of the local load to other WSD DS/WSD NP devices that are served by this WSD DS / WSD NP.

Load Report Timeout – The time (in seconds) this device will wait to receive load reports from a remote device. After this timeout, the remote device is considered to be not responding. According to the number of retries configured in the farm, the remote WSD DS / WSD NP becomes inactive (similar to the connectivity checks of regular servers).

Interface Grouping – When enabled, a second redundant unit backs up this WSD for some of its farms. The failure of any network interface will result in the failure of the entire device, enabling the redundant unit to take over all activity.

Nat Operation – The WSD also supports outgoing sessions initiated by the internal servers. If the servers' addresses are illegal addresses, this might be impossible to do. When Nat status is enabled, the WSD will send the sessions out using the virtual address, and will actually operate as a NAT device.

Client Grouping Mask – You can specify a subnet mask such that all clients with this subnet who access a particular farm are redirected to the same server in that farm.
