Hello,
I config a revers dns im my domain, but him pointer to external server. Check all dns, virtual servers and apache configurations and dont find where it pointer to out.
I too check with:
# host -t ptr 4.204.120.64.in-addr.arpa
4.204.120.64.in-addr.arpa domain name pointer srv.businessconnection.com.br.
Should point to another server, this no is the correct!

I make equal config another server and work very well, but in this are some erro. Somebody know what I doing wrong?

Thanks!

looks like burst.net is authoritative for the whole 64.120.204.0/25 subnet. You should have the delegation of a chunk of this subnet depending on how many static IPs you have given.
So unless you talk to them you cannot setup a reverse zone for their subnet.
