Support for Windows 7
Kerio WinRoute Firewall now includes full support for the new operating system Microsoft
Windows 7 .
2.2 Conflicting software
WinRoute can be run with most of common applications. However, there are certain applica-
tions that should not be run at the same host as WinRoute for this could result in collisions.
The computer where WinRoute is installed (the host) can be also used as a workstation. How-
ever, it is not recommended — user interaction may affect performance of the operating sys-
tem which affects WinRoute performance badly.
Collision of low-level drivers
WinRoute 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.
WinRoute 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 ).
WinRoute can detect if NAT is active in the RRAS service; if it is, a warning is dis-
played. 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 WinRoute 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 appli-
cations 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 WinRoute is
recommended (for details see chapter 23 ). Otherwise, we recommend you to test
a particular VPN server or VPN client with WinRoute trial version or to contact
our technical support (see chapter 26 ).
Note: VPN implementation included in Windows operating system (based on the
PPTP protocol) is supported by WinRoute .
Port collision
Applications that use the same ports as the firewall cannot be run at the WinRoute host
(or the configuration of the ports must be modified).
If all services are running, WinRoute uses the following ports:
