Custom Rules

Fine grained control over individual domain names.

What are Custom Rules

Custom Rules are the basic building blocks of Control D, and allow you to create fine grained rules for specific domain names. Think of these as a hosts file in the cloud, with wildcard support.

Rule Actions

Much like with Services (which are just collections of Custom Rules), one of 3 rule types can be attached to any domain name.

Block

A BLOCK action will prevent the domain from loading, and will effectively make it inaccessible from a Device that enforces a Profile.

Bypass

A BYPASS rule will resolve the domain to its true IP address from Authoritative DNS. This is useful to override Filters, Services, or the Default Rule.

Redirect

A REDIRECT rule will spoof the domain via a proxy location or specific IP address chosen by you.

Custom Rules can be grouped into Folders, which can have their own actions.

Rule Format

Custom rules can be exact or use wildcards. All of the following are valid:

  • domain.com -> BLOCK - would block just domain.com (in the future, right now it's treated as *.domain.com)
  • *.domain.com -> BLOCK - would block all subdomains (unlimited levels) of domain.com but NOT domain.com itself.
  • server-*.domain.com -> BLOCK - would block server-01.domain.com and server-anything-goes-here.domain.com
