Does the Initiate of the Sevenfold Veil's Indigo Veil protect against supernatural abilities?

Question

The Initiate of the Sevenfold Veil (Complete Arcane) has a "Indigo Veil" ability which provides a protection against incoming spells and spell-like abilities:

Indigo Veil: A 6th-level initiate can create the mighty indigo veil. This veil prevents the passage of all spells or spell-like abilities. Any creature crossing an indigo veil must succeed on a Will save or become confused, as if by an insanity spell. A daylight spell negates and is negated by an indigo veil. A warding with this veil is the equivalent of a 7th-level spell.

Does this also protect them from supernatural abilities?

Answer 1

No. A supernatural ability is not a spell-like ability, therefore it is not affected by the Indigo Veil which explicitly calls out spells and spell-like abilities.
