Subdomain to 2nd server
Assume I have ISPC3 on a Centos box with 192.168.1.4 and domain example.tld as the main server. In the same LAN there is my CALDAV-server with 192.168.1.2. How can I tell ISPC3 to route caldav.example.tld to 192.168.1.2?
I followed a hint creating a DNS record: "Login to ispconfig, go to the dns manager, edit the zone were the subdomain shall be added, go to the records tab and click on the "A" button. Then enter: 'Hostname: caldav' / 'IP address: 192.168.1.2' You can test this with dig after you waited a few minutes."
DIG does not show any change and the browser still shows the 192.168.1.4 website. Even after ten minutes.
