Any entry in a set can be bound to another set, which forms a relationship
between a set element and the set it is bound to. In order to define a
binding it is not required that the entry be already added to the set.
The sets may have a default binding, which is valid for every set element
for which there is no binding defined at all.
.P
IP set bindings pointing to sets and iptables matches and targets
referring to sets creates references, which protects the given sets in
the kernel. A set cannot be removed (destroyed) while there is a single
reference pointing to it.
.P
.B
Please note, binding sets is a deprecated feature and will be removed in a later release. Switch to the multidata type of sets from using bindings.
Iptables matches and targets referring to sets creates references, which
protects the given sets in the kernel. A set cannot be removed (destroyed)
while there is a single reference pointing to it.
