Forwarding is only done for zones the server isn't authoritative for.
Since the LAN server is authoritative for isokiti.tv, it never forwards
anything in this zone. You even said this up above, when you described
what you wanted to do.
You'll need to copy all the records from the DMZ server to the LAN
server.
