Specifies the global default value of where the last S port is before the one or two ports specified in LivingstonHole are skipped (usually 22 for US, 29 for Europe).

Defaults to 29.This value can be overridden on a per-Client basis by using LivingstonHole in a Client clause. For more information, see Section 3.14.42. LivingstonOffs.
