Multiple Sections may be included in any SubStanza. A “Default” Destination Interface Name Section may be specified. NOTE: Do not include the quotes when specifying Default.

The NetMask must be specified in Decimal Dot IP Address Notation

All SubSections must be specified in every Section.

Network Options Stanza Example:

NOTE: Tuning is a “fine art” and may vary dramatically within any network configuration and may change with only very minor network configuration modifications. Values provided below are not necessarily “good” numbers!
