Warning
Changes in the routing table might interrupt the connection between the WinRoute Firewall
Engine and the Administration Console. We recommend to check the routing table thoroughly
before clicking the Apply button!
Route Types
The following route types are used in the WinRoute routing table:
•
System routes — routes downloaded from the operating system’s routing table (includ-
ing so called persistent routes). These routes cannot be edited some of them can be
removed — see the Removing routes from the Routing Table section).
•
Static routes — manually defined routes managed by WinRoute (see below). These
routes can be added, modified and/or removed.
The checking boxes can be used to disable routes temporarily —such routes are pro-
vided in the list of inactive routes. Static routes are marked with an S icon.
•
VPN routes — routes to VPN clients and to networks at remote endpoints of VPN tun-
nels (for details, see chapter
). These routes are created and removed dynamically
upon connecting and disconnecting of VPN clients or upon creating and removing of
VPN tunnels. VPN routes cannot be created, modified nor removed by hand.
•
Inactive routes — routes which are currently inactive are showed in a separate section.
These can be static routes that are temporarily disabled, static routes via an interfaces
which has been disconnected or removed from the system, etc.
Static routes
WinRoute includes a special system for creation and management of static routes in the routing
table. All static routes defined in WinRoute are saved into the configuration file and upon each
startup of the WinRoute Firewall Engine they are added to the system routing table. In addition
to this, these routes are monitored and managed all the time WinRoute is running. This means
that whenever any of these routes is removed by the route command, it is automatically
added again.
Note:
1.
The operating system’s persistent routes are not used for implementation of static routes
(for management of these routes, WinRoute uses a proprietary method).
2.
If a static connection uses a dial-up, any UDP or TCP packet with the SYN flag dials the
line. For detailed information, see chapter
