Hi!
Never use if ($host ...
Different servers with different server_names must be used instead:
server
{
    server_name forum.de;
    location / { rewrite ^ http://www.forum.de:81/$request_uri? premanent; }
}
server
{
    server_name ~^(www\.)??forum\.(at|ch|com|eu|info|net|org);
    location / { rewrite ^ http://www.forum.de:81/$request_uri? premanent; }
}
