Unclear documentation on putting Iodine behind another nameserver

I'm trying to get Iodine working again after changing servers, and I'm unable to figure out what setup I had before this. I'm running BIND on port 53 and Iodine on port 54, and in my `named.conf` I have two zones: `t1.example.com` for Iodine, and then `example.com` for all my other stuff. The `t1` zone is forward only to 127.0.0.1 port 54, but I can't get Iodine and BIND to work together properly. What am I missing here? The documentation on this setup is pretty vague, but I can't out Iodine in front of BIND because I need zone transfers to work.
