The reason for writing this material were quite frequently encountered problems and disruptions in access to the Internet using one ADSL provider. In addition, the policy itself providers, both tariff and in terms of customer support, frankly, rude. So I set out to get faster, and most importantly reliable access to the network, by combining the two channels on the Internet from different providers into one. This will not only increase the stability and reliability of access to the network, but also will enable balance by choosing always the most suitable tariff plan for the primary and alternate channels of access to the Internet.

Order that would “merge the two real providers” in a “one virtual”, you need a router equipped with two ports WAN. Examining all the available supply in the market Dual WAN routers, model was chosen DrayTek Vigor2910, as the best and most affordable option with the best value for money-functionality. As an ADSL modems use two small black boxes called Zyxel Prestige 660RT EE. It is worth noting that, by analogy can be combined into a one-channel “all other providers, such as ADSL and cable providers such as the Ukrainian” Freedom “. You can even as a second WAN-and use 3G cellular modem. With all these tasks Vigor2910 copes very well. My ultimate goal was to combine two Internet bandwidth from DSL providers, so we just go on like this.
Of available at my providers were selected Ukrtelecom providing services under the brand name of CSOs and the company Farlep, a member of the telecommunications group Vega. Next, we will call providers Ukrtelecom and Vega. Each of the providers have a sea of pluses, and the same sea of deficiencies. The union of two lines from Ukrtelecom and Vega can get Internet access service with quality that will satisfy most people for whom the network is not just a game, and what more.
Before you configure the modem and router, in the properties of TCP / IP network card main PC prescribed parameters by analogy, as indicated in the figure below.

Now both the modem Zyxel Prestige 660RT EE set up in bridge mode (Bridge), in any case not as a router (Router), just as bridges, because responsible for the authorization and the rise of PPPoE sessions will be our smart router DrayTek Vigor2910. In the setting of LAN TCP / IP pore modem, in this case connected to the ISP Vega, prescribes and IP Address 192.168.1.1 IP Subnet Mask 255.255.255.0. WAN settings do as picture below.

Similarly, for the second modem, in this case connected to the ISP Ukrtelecom, prescribes and IP Address 192.168.1.2 IP Subnet Mask 255.255.255.0. WAN settings do as picture below.

Now computer and modem are ready and tuned, it’s time to configure the router Vigor2910. LAN Settings router performs as picture below.

Connecting the first modem to the port Vega WAN1 router, and the second Ukrtelecom port WAN2.
We insist «WAN>> General Setup», as shown in the figure below and click OK

Now in the menu «WAN>> Internet Access», for both ADSL providers are asking Access Mode PPPoE.

For each of the providers we press the button «Details Page» and prescribes your username and password to access all other settings are similar as in the screenshots below for providers Ukrtelecom and Vega.


Now the important point. It is necessary to adjust the rules through the WAN port to “walk in the Internet”, depending on the remote address. As you know, Ukrtelecom and Vega have the resources to which access is open only to local clients as well as balancing between the channels automatically, you can go into a closed network of Vega through Ukrtelecom or vice versa, resulting in access will be denied. For what would such an incident does not happen in «WAN>> Load-Balance Policy» define rules for where and how to walk. For providers Ukrtelecom and Vega settings can be taken as in the screenshot below. The second line is ignored, it is a special case, where fixed rules across a WAN port connect to the Internet referring to my personal server that you do not need.

Save and reboot, wait 10 seconds, countertop and look System Status of our router in your browser.

You can see that target reached, and now my PC and all devices connected to a router, working with two providers Ukrtelecom and Vega as one, simultaneously with load balancing.
I hope this material will be useful to those who confront a similar problem. I once could not find a network such material. I had to write yourself.
For more information, post the data obtained from the Web interface Router DrayTek Vigor2910, the first screenshot, and a few screenshots program DrayTek SysLOG, which will help visually understand how the Load-Balance Policy.

Program DrayTek Syslog 4.2.0 and Load-Balance Policy.
