I am wading through tons of material to improve my knowledge of Linux networking in general and more specifically to configure our firewalls properly and routing for multiple uplink providers with traffic shaping and failover.我涉水通過噸的物質，以改善我所知， Linux的網絡在一般和更具體的配置我們的防火牆，妥善和路由多個上行供應商與流量整形及故障排除。

My earlier attempt to shortcut with我剛才企圖的捷徑 eBox ebox failed so this time I am going all the way.失敗，所以這個時候我所有的方式。 Expect more articles on these arcane topics in the coming days.期望更多文章，對這些難懂的課題，在未來的日子。

In the meantime if you can offer me a simple way to route multiple uplink providers with load balancing and transparent fail over that would be highly appreciated.在此期間，如果您可以提供我一個簡單的方法來路線上行多個供應商與負載平衡和透明的不能超過這將是高度讚賞。 Each of my DSL modems have been configured as a router & gateway with NAT enabled.我的每個DSL調製解調器已配置為路由器及網關的NAT啟用。 So I don’t even have to mess with adsl commands.因此，我不，甚至要一塌糊塗，與ADSL的命令。 They are always up.他們總是最多。

In the process I will also have to setup my internet machine as a gateway for the intranet.在這個過程中，我會也有設置我的Internet機作為一個門戶聯網。 Previously I used以前我用 firestarter FireStarter - . 。 However that doesn’t work with multiple uplink providers.不過，這並不工作，與多個上行供應商。

I need to route certain traffic like sftp / scp through a particular (higher speed) interface.我需要某些交通幹線一樣， SFTP發布/ SCP的通過，尤其是（高速）接口。 While browsing can use either.而瀏覽可以使用。 Downloading should use the higher speed interface.下載，應使用較高的高速接口。 Traffic needs to be balanced 4:1 across the interfaces which is proportionate to their relative speed.交通需求加以平衡4:1整個界面是相稱，以它們的相對速度。 In case you are wondering why I have the slower connection it is simply for redundancy.在情況下，您是為什麼我有慢，連接這只不過是冗餘。

Any suggestions and ideas welcome (which is why I have written this post).任何的建議和想法表示歡迎（這就是為什麼我寫了這個職位） 。

PS.保安局常任秘書長。 In case you are wondering about the complexity of the endeavor on Linux I don’t think you can even do them in Windows.在情況下，您是不知道有關的複雜程度，努力在Linux上我不認為你甚至可以做他們在Windows 。
