4.6 User counter
This chapter provides a detailed description on how WinRoute checks whether number of
licensed users has not been exceeded.
The WinRoute license does not limit number of user accounts. Number of user accounts does
not affect number of licensed users.
Warning
The following description is only a technical hint that may be used for troubleshooting. License
policy must be borne in mind when deciding for a license purchase — see chapter
!
The license counter works as follows:
Start WinRoute
Upon WinRoute is started, the table of clients include the firewall only. Number of used li-
censes is zero.
Note: Table of clients is displayed in the Active Hosts section in the Administration Console —
see chapter
License counter
Whenever a communication of any WinRoute’s client is detected, the IP address is used to iden-
tify whether a record does already exist in the table of clients. If not, a new record including
the IP address is added to the table and the number of licenses is raised by 1.
The following items are considered as clients:
1.
All hosts from which users are connected to the firewall
2.
All clients of the WinRoute’s proxy server (see chapter
3.
All local hosts communication of which is routed between Internet interfaces and
WinRoute’s local interfaces. The following items belong to this group:
•
Each host which is connected to the Internet while no user is authenticated from
the host,
•
All local servers mapped from the Internet,
•
All VPN clients connected to the local network from the Internet.
Licenses are not limited by:
•
DNS requests handled by the DNS module (Warning: If clients use a DNS server located
outside the local network, such communication is considered as communication with
the Internet),
•
DHCP traffic (using either the WinRoute’s DHCP server or another DHCP server in-
stalled on the WinRoute host),
•
Local communication between the firewall (e.g. access to shared disks) and hosts from
which no user is connected to the firewall.
