The access over the internet to my dsl router works with dyndns.
But i want to set up a connection to an other host in my local network,
This connection should be over a name DNS name.
For example if my dyndns is xyz.dyndns.com the connection to the internal server should be with server.xyz.dyndns.com.
If your ISP will only give you one IP address, then there is no point in having two different hostnames (they must both resolve to the same single IP address). You can differentiate between the two computers by the port number. e.g. If you connect to port 80 you get the web server, but if you connect to port 25 you get the mail server. This is all done with port-forwarding in the router/firewall. If the router/firewall is a linux box, you do it with iptables (using DNAT).
