Hi Ben, thanks for reply but DNS solution is not exactly what i need, because then you are not able to use port forwarding option. This is important if you are using different services on separate servers. For example under FQDN name mail.mydomain.com I have mailserver on internal server1 but webmail is on internal server2. So I need to forward requests to ports 25,465,995,993 to server1 but requests for port 80,443 to server2. So DNS solution is usable only in simple scenarios.
