6.1  Persistent connection with a single link

Requirements

The WinRoute hosting computer must be connected to the Internet by a leased line (typically Ethernet or WiFi card). Parameters of this interface will be set with use of information supplied by the ISP provider or they can be configured automatically with the DHCP protocol.

It is also possible to use a dial-like link which can be connected persistently, such as PPPoE connections or CDMA modems. WinRoute will keep this type of link connected persistently (in case of connection failure, the connection is automatically recovered immediately).

This connection type also requires one or more network cards for connection of individual segments of the LAN. Default gateway must NOT be set on any of these cards!

If possible, it is also recommended functionality of the Internet connection before installing WinRoute.

Configuration with the wizard

On the second page of the Traffic Policy Wizard (see chapter 7.1  Network Rules Wizard), select A Single Internet Link — Persistent.

On the third page of the wizard, select a network interface (Internet link). As a preselection, the interface where WinRoute detected the default gateway is used. Therefore, in most cases the appropriate adapter is already set within this step.

If you select a link which is defined as a dial-up (see above), valid username and password are required. If this information is saved in the operating system, WinRoute can enter it automatically.

In the Software Appliance / VMware Virtual Appliance edition, the wizard allows:

  • to configure parameters of the selected interface,

  • to create a new interface (PPPoE, PPTP or dial-up).

For details on network interfaces, see chapter 5  Network interfaces.

Notes:

  1. On the top of the list, the Internet interface where the default gateway is set is offered. Therefore, in most cases the appropriate adapter is already set within this step.

  2. If the more IP addresses are set for the interface, the primary IP address will be displayed. On Windows, the address assigned to the interface as first is considered as primary.

  3. The other pages of the Traffic Policy Wizard do not concern Internet connection type. They are focused in detail in chapter 7.1  Network Rules Wizard

Resulting interface configuration

When you finish set-up in Traffic Policy Wizard, the resulting configuration can be viewed under Configuration → Interfaces and edited if desirable.

The Internet Interfaces groups includes only card Internet selected in the third page of the wizard. Other interfaces (including Dial-In) are considered as segments of the LAN and put in Trusted / Local interfaces.

If the setting does not mirror the real configuration of the network correctly (for instance there is an interface planned for DMZ), you can move the particular interface to Other Interfaces. For these interfaces, it will be necessary to define corresponding traffic rules manually (see chapter 7.3  Definition of Custom Traffic Rules).

It is also possible to add new interfaces to the Internet Interfaces group. Packets will then be routed to corresponding target networks in accordance with the system routing table (see also chapter 18.1  Routing table) and IP address translation will be applied (NAT). However, such configuration is not significantly helpful in place.

Warning

It is necessary that in the Single internet Link mode the default gateway is set only at the “main” Internet interface! If WinRoute detects more default gateways, error is announced. Solve this problem immediately, otherwise traffic from the firewall and the LAN to the Internet will not work correctly.
