2.2 Conflicting software
Warning:
Since 6.x, some configuration parameters have been changed in version for 7.0.0. Although
updates are still performed automatically and seamlessly, it is necessary to mind these tiny
changes. Detailed information:
• Edition for Windows — see chapter 2.6,
• Edition for Software Appliance / VMware Virtual Appliance — see chapter 2.8.
After update, it is recommended to check Warning log carefully (see chapter 22.13).
2.2 Conflicting software
Kerio Control can be run with most of common applications. However, there are certain
applications that should not be run at the same host as WinRoute for this could result in
collisions.
The computer where Kerio Control is installed (the host) can be also used as a workstation.
However, it is not recommended — user interaction may affect performance of the operating
system which affects Kerio Control performance badly.
Collision of low-level drivers
Kerio Control collides with system services and applications the low-level drivers of
whose use a similar or an identical technology. The security log contains the following
types of services and applications:
• The Internet Connection Firewall / Internet Connection Sharing system service.
Kerio Control can detect and automatically disable this service.
• The system service Routing and Remote Access Service (RRAS) in Windows Server
operating systems. This service allows also sharing of Internet connection (NAT).
Kerio Control can detect if NAT is active in the RRAS service; if it is, a warning
is displayed. In reaction to the alert message, the server administrator should
disable NAT in the RRAS configuration.
If NAT is not active, collisions should be avoided and Kerio Control can be used
hand in hand with the RRAS service.
• Network firewalls — e.g. Microsoft ISA Server.
• Personal firewalls, such as Sunbelt Personal Firewall, Zone Alarm, Norton Personal
Firewall, etc.
• Software designed to create virtual private networks (VPN) — i.e. software
applications developed by the following companies: CheckPoint, Cisco Systems,
Nortel, etc. There are many applications of this type and their features vary from
vendor to vendor.
Under proper circumstances, use of the VPN solution included in Kerio Control
is recommended (for details see chapter 23). Otherwise, we recommend you to
