Windows Task Manager. Under specific circumstances, such application might also
block other dials or hang-ups.
Edit Interface parameters
Click Edit to modify parameters of a selected interface. The Interface properties dialog,
identical with the dialog for adding of a new RAS dial-up, is opened in case of RAS
dial-ups. Only the Interface name entry can be edited in case of network adapters.
For VPN server and VPN tunnels, a dialog for setting of the VPN server (see chapter 21.1)
or a VPN tunnel (refer to chapter 21.3) will be opened.
5.2 Connection Failover
WinRoute allows for definition of connection failover (secondary connection). This sec-
ondary connection is enabled automatically whenever a dropout of the primary Internet
connection is detected. Functionality of the primary connection is tested by sending of
ICMP Echo Requests (PING) to selected computers. When WinRoute finds out that the
primary connection is recovered again, the secondary connection is disabled and the
primary one is established automatically.
Any network interface or dial connection defined in WinRoute can be used as an sec-
ondary connection (see chapter 5.1). Traffic rules permitting or denying relevant com-
munication through the secondary connection must be defined. In other words, it is
necessary to add an interface for secondary connection to each rule where an interface
for primary connection is included in the Source or/and Destination column.
For detailed information about traffic rules, refer to chapter 6.3.
Example: Primary connection used for traffic going out to the Internet is performed by
a network adapter (labeled as Internet in WinRoute). A Dial-up Connection interface will
be used for the secondary connection. We want to deny the Telnet service in direction
from the local network to the Internet.
This situation is shown by traffic rules at figure 5.7. Two destination items are specified
for each rule: network connected to the Internet interface (primary connection) and
network connected to the Dial-up Connection interface (secondary connection).
• NAT — translation of source IP addresses will be performed for connections from
the local network to the Internet (shared Internet connection).
• Firewall traffic — the WinRoute host will be allowed to connect to the Internet (NAT
is not necessary since this host has its proper IP address).
