Any process that activates or increases the frequency, rate or extent of the directed movement of iron ions from one side of a membrane to the other by means of some agent such as a transporter or pore.

Any process that activates or increases the frequency, rate or extent of cation transmembrane transport.

Any process that modulates the frequency, rate or extent of the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of iron ions from one side of a membrane to the other by means of some agent such as a transporter or pore.

Any process that stops, prevents or reduces the frequency, rate or extent of cation transmembrane transport.

Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.

Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
