Introduction
2.1 Kerio WinRoute Firewall
Kerio WinRoute Firewall 6.0 is a complex tool for connection of the local network to the Internet
and protection of this network from intrusions. It is developed for Windows systems (since
version 2000 ).
Basic Features
Transparent Internet Access
With Network Address Translation (NAT) technology, the local private network can be
connected to the Internet through a single public IP address (static or dynamic). Un-
like proxy servers, with NAT technology all Internet services will be accessible from any
workstation and it will be possible to run most standard network applications, as if all
computers within the LAN had their own connection to the Internet.
Security
The integrated firewall protects all the local network including the workstation it is in-
stalled on, regardless of whether the NAT function (IP translation) is used or WinRoute is
used as a neutral router between two networks. Kerio WinRoute Firewall offers the same
standard of protection found in much more costly hardware solutions.
Relay Control tab
All the security settings within WinRoute are managed through so-called traffic policy
rules. These provide effective network protection from external attacks as well as easy
access to all the services running on servers within the protected local network (e.g. Web
Server, Mail server, FTP Server, etc.). Communication rules in the traffic policy can also
restrict local users in accessing certain services on the Internet.
Bandwidth Limiter
Typically, problems with Internet connection arise when a user attempts to download big
volume of data (installation archive, disk image, audio/video file, etc.) and thus the con-
nection to the Internet and to other server services is slowed down for other users. The
WinRoute’s built-in Bandwidth Limiter module enables to reserve bandwidth for transfer
of big size data. The rest of the bandwidth will be constantly available for other services.
Protocol Maintenance (Protocol Inspectors)
You may come across applications that do not support the standard communication and
that may for instance use incompatible communication protocols, etc. To challenge this
problem, WinRoute includes so-called protocol inspectors, which identify the appropriate
application protocol and modify the firewall’s behavior dynamically, such as temporary
