setup openvpn with your dyndns as VPN client that way you have a fixed IP besides it solves the IP problem zone transfers are more safe because they are encrypted and can't get mangeled by broken crap like cisco routers doing DNS ALG look at the archives, i had recently the fun that a cisco router between master/slave instisted to manipulate zone transfers and set every CNAME a zero TTL
