Subdomain not working

I have created a new subdomain in my ISPconfig 3 as follows:

Host: webmail
Domain: mysite.net
Redirect type: R,L
Redirect path: hosting.myserver.com/webmail
Active: yes

Nothing seems to get through. At the address specified, I get a "server not found".
Do I also need to set-up DNS separately? Should this not be done through the vhosts configuration?

Code:

" ============================================================================
" Netrw Directory Listing                                        (netrw v136)

yes, you do need to create a DNS entry for it .. create an "A" record pointing at the ipaddress your site is located on, leave the TTL and check "active" with the hostname webmail.shannonlynn.net

are you managing your domain through your dns server or do you one from the provider you bought the domain from?

 

OK, works now.

This was unclear in documentation and I had already tried it without success.

I must have fat-fingered something on my previous attempt to create an a-record for webmail!
