Once your order has been provisioned, you will need to login to members portal at https://members.softsyshosting.com/clientarea.php -> Navigate to the service (Services -> My Services), click on CloudFlare With WAF service and thereafter click "Open Control Panel" link. Thereafter, click on "ServerShield By CloudFlare" link on right hand side menu and enable CloudFlare (if not already done) by entering your preferred username / password.
Please note below about few important points:
1) This is setup through special CNAME flattening process and will not require you to update name servers of your domain to that of CloudFlare.
2) Per RFC standards, domain.com (without www) cannot be protected behind CloudFlare - hence, you will need to create a 301 permanent redirect to redirect all requests to domain.com forwarded to www.domain.com - this can be easily achieved with URL Rewrite (Windows) or .htaccess (Linux systems) - there are plenty of online sample codes available for this.
3) For each domain or subdomain that you want to protect with CloudFlare, you will need to ensure that relevant CNAME records are created with your DNS provider along with creating the same in Plesk Panel + enabling CloudFlare for the sub-domain from Plesk Panel (noted above).
CloudFlare is enabled by default for www.domain.com when the plan is activated. Please take a note of below DNS records to be created / updated with your DNS provider in order to route traffic through CloudFlare:
1) Update or create www record (A / CNAME) to point to below:
Type: CNAME
Record Name: www
Value: www.<yourdomain.com>.cdn.cloudflare.net
2) Create a new CNAME / A record as below:
Type: CNAME
Record Name: cf
Value: yourdomain.com
——— OR ———
Type: A
Record Name: cf
Value: <<IP-Address-Of-Website-www.yourdomain.com>>
The above will point all traffic on www to cloudflare which will be calling for actual server data from cf.yourdomain.com.
In case you want to have a sub-domain (eg. blog.yourdomain.com) to be protected through CloudFlare, create below records (along with enabling it in Plesk Panel as outlined above):
1) Update or create blog record (A / CNAME) to point to below:
Type: CNAME
Record Name: blog
Value: blog.<yourdomain.com>.cdn.cloudflare.net
2) Create a new A record as below:
Type: A
Record Name: cf
Value: <<IP-Address-Of-Website-blog.yourdomain.com>>
