Hello One of the sites on my ISPConfig 3 server will only be a sub domian. *.domain.com is hosted on another server. sub.domain.com will be hosted on this ISPConfig server. How would I set this up?
Point your subdomain A record to ISPConfig server, than click on Add New Website in ispconfig. In domain field type the subdomain.domain.com and choose none in Auto-Subdomain. That's it.
i have exactly your setup me too, and doing as said by damir worked perfectly. i also added in the external dns an MX record for the sub.domain.com who points to ispconfig server in order to manage mails sent to: [email protected] ( i have different subdomains hosted in ispconfig server, for each i have related website and mail) bye.
