HOW DOES FILTERING WORK?
1. A provider installs GateWall DNS Filter in its real or virtual server. A
cluster may as well be organized.
2. Standard restriction schemes are set (dangerous websites, pornography,
media content, entertainment websites, etc.)
3. On the provider’s DNS server the rules are created through which the
requests from service users are forwarded to a server with a GateWall
DNS Filter, where the required settings and restrictions are applied,
respectively.
5. All DNS-requests related to forbidden websites are blocked

HARDWARE REQUIREMENTS
The request rate for different users may vary considerably.
Here are the rough data for server requirements:
 100 users -> CPU > 2 GHz; RAM - 2Gb
 1000 users -> CPU > 2 GHz; RAM - 4Gb
 10000 users -> CPU > 2 GHz; RAM - 8Gb
We recommend having free disk space for statistics data storage in the
ratio of monthly 1.5Gb per 100 users. Thus, for storing 6-month statistics
of 10,000 users a provider would need 900Gb of disk space.
GateWall DNS Filter can be installed both on the physical and virtual
machines.
