Protocol Maintenance (Protocol Inspectors)
You may come across applications that do not support the standard communi-
cation 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 dy-
namically, such as temporary access to a specific port (it can temporarily open the
port demanded by the server). FTP in the active mode, Real Audio or PPTP are just
a few examples.
Network Configuration
WinRoute has a built-in DHCP server, which sets TCP/IP parameters for each work-
station within your local network. Parameters for all workstations can be set cen-
trally from a single point. This reduces the amount of time needed to set up the
network and minimizes the risk of making a mistake during this process.
DNS forwarder module enables easy DNS configuration and faster responses to
DNS requests. It is a simple type of caching nameserver that relays requests to
another DNS server. Responses are stored in its cache. This significantly speeds up
responses to frequent requests. Combined with the DHCP server and the system’s
HOSTS file, the DNS forwarder can be also used as a dynamic DNS server for the
local domain.
Remote Administration
All settings are performed in the Kerio Administration Console, an independent
administration console used to manage all Kerio’s server products. It can be run
either on the workstation with WinRoute or on another host within the local network
or the Internet. Communication between WinRoute and the administration console
is encrypted and thus protected from being tapped or misused.
Various Operating Systems Within The Local Network
WinRoute works with standard TCP/IP protocols. From the point of view of work-
stations within the local network it acts as a standard router and no special client
applications are required. Therefore, any operating system with TCP/IP, such as
Windows, Unix/Linux, Mac OS etc., can be run within the LAN.
Note: WinRoute can work with TCP/IP protocol sets only. It does not affect the function-
ality of other protocols (i.e. IPX/SPX, NetBEUI, AppleTalk, etc.).
Additional Features
HTTP and FTP filtering
WinRoute can monitor all HTTP and FTP communication and block objects that do
not match given criteria. The settings can be global or defined specifically for each
user.
