Problems forwarding zone to another DNS server

I have a authorative DNS server at 83.248.21.18 which are authorative for the domain "finahemgoteborg.se". Now my registrar is requiring me to have 2 DNS servers for the domain, so I would now want the machine 85.228.103.141 just forward all incoming queries for "finahemgoteborg.se" to the 83.248.21.18 server.

In the 85.228.103.141 BIND server, I have the following config:

zone "finahemgoteborg.se" in {
type forward;
forwarders {83.248.21.18;};
};

But the problem is that 85.228.103.141 is still responding with "REFUSED" when querying it for example www.finahemgoteborg.se A record.

How can I fix it. I do NOT want to set up a master/slave situation, just one nameserver that forwards to a another.

Edit The Rest of named.conf:

options {
  directory "/var/cache/bind";  
  version "none";
  allow-recursion {"none";};
  minimal-responses no;
};

zone "sebn.us.to" in{
  type master;
  file "/etc/bind/sebn.us.to";
};

zone "ns1sebn.us.to" in{
  type master;
  file "/etc/bind/sebn.us.to";
};

zone "ns2sebn.us.to" in{
  type master;
  file "/etc/bind/sebn.us.to";
};

zone "finahemgoteborg.se" in{
type forward;
forwarders {83.248.21.18;};
};
