You are right in that you only need one host at dyndns.org to update
your ip address, but you want to have two different websites. The
proper
way to do that is with CNAME entries pointing to the host you are
updating at connect time.
Do i need to open my firewall for port 53? :-( Is there another way?
maybe to add two virtual hosts at dyndns.org with the same IP?

I don't know dyndns.com services that well. I don't know what they
support or do not support directly.
Using an example, I have lcrcomputer.com. If I setup a dynamic dns host
with dyndns.org and wanted two host names pointing there, I would do
this:
1) setup a dynamic host at dyndns: host.dyndns.org
2) in the LCRCOMPUTER.COM zone I would add two entries:
host1.lcrcomputer.com. in cname host.dyndns.org.
host2.lcrcomputer.com. in cname host.dyndns.org.
In which zone file? "db.feldland.lan" or in "db.192.168.0" ? or in both?
db.192.168.0 is for reverse lookups. Mapping ip addresses to a host
name. 192.168.0.x is part of RFC1918 reserved ip addresses and should
never be exposed to the Internet.
db.feldland.lan is a private internal to your lan domain that is not
registered anywhere and therefore nobody out on the Internet should be
looking for hosts there.
In my example, LCRCOMPUTER.COM is a legal and registered domain name on
the Internet.
And would it be possible to only allow the DNS-Server at dyndns.org and
my provider to contact my bind9 server and not to the rest of the world?
Or does it make no sense for name resolving?
We have not established a sane question for them to ask of your name server.
