Well, NOTIFY doesn't "only work[s] for master", it works for slaves too, 
but by default the NOTIFYs get sent only to the servers mentioned in the 
NS records of the zone. If you're NAT'ing, maybe you're sending the 
NOTIFYs to the external addresses instead of the internal addresses, or 
something like that. Note that you can override the default NOTIFY 
behavior with BIND's "also-notify" alone, which would be purely 
additive, or "also-notify" together with "notify explicit", which 
completely *replaces* the default NOTIFY list.
