Most normal DNS traffic uses UDP not TCP. However AXFR uses TCP

yes, TCP 53 is needed for zone transfer "slave type", but I couldn't find any info about protocol used for r" forward type"

I think sub-zone using forwaders is not going to work.
I ended up using sub-zone delegation, which use UDP only.
