Hmmm, I thought that this CSW post addressed it...

The rules say enemy units in pillboxes generate VOF in only one direction. If friendly units are in the same card, does the enemy unit in pillbox generate VOF ?
Can friendly units attempt grenade attacks against enemy in pillboxes ?
If so, can enemy in pillboxes throw back grenades ?
Yes - A pillbox will have supporting positions around it
Tho I suppose "...does the enemy unit in pillbox generate VOF ?" could be interpreted to mean the pillbox keeps shooting outside the card. But I'm thinking the simpler interpretation is probably correct: the pillbox puts VOF on its own card.
