Topic: DUAL WAN

[JP]

i have searched high and low for a means or technology to combine two or more internet connections into one.

this is what i want to do: purchase 2 dsl connections and run them all into a linux box where all the channels would be bonded
and a 3rd nic would be used for the output of the bonded internet connection.


Can u help me ?

I know of only one line type that can be bonded in a linux server and that is a T-1 using something like a Cyclades PC-300 Dual T-1/E-1 interface card using mlppp as the line protocol.  You can create a server that does load balancing, but you will not see any speed improvements.  There is also a device out on the internet by Nexland called an ISB PRO 800.  This router has a dual wan port and does load balancing or fail-over, but once again no speed improvements.

There are some software packages for windows that do what you want, such as Intergate by Vicomsoft (http://www.vicomsoft.com).

I presume you mean "full on" business adsl, as these are usually more expensive but you are allocated a full 512Kb (or whatever), so 2 x 512 = 1Mb.  If it is residential adsl don't bother, in the IoM as many as 50 users can share this 512Kb bandwidth

Be very careful with the terminology that is used when describing these types of devices. I have spent a lot of time researching this topic and it is rife with misunderstanding and deception. Very simply put there are two categories, load balancing and load aggregation. Almost all the devices that you will run into will do load balancing or what is effectively load distribution across multiple WAN connections. In this configuration the dual-wan routers can't provide peak speed on a single data transfer any higher than the fastest single WAN connection. Download managers can efficiently utilize this kind of configuration but it does not mean that you suddenly have twice the speed. The Xincom router has some nice options but when it comes to true WAN aggregation you are talking about thousands of dollars and ideally require cooperation from your ISP. The best results will come from multiple connections from a single ISP as opposed to services from multiple ISP's. I have seen a few Linux projects attempting to achieve what you are talking about but they have all fizzled out. This is something that can be done but it is not an easy task.

If you find anything I would love to hear about it.

Keep the faith.

I just want to know if you are able to have this kind of connection since April???  Right now, our company is planning to purchase another dsl connection and instead of buying a new product for Dual WAN, we are thinking of using SME 6.0.  Is it possible to have this kind of features in SME 6.0???

I will be glad to hear from you...

An answer for nald.

I wish it weren't the case but the answer is no. I would also suggest being a little more specific about how you intend to configure the DSL services (load balance vs. aggregate). Read my last post for details. This is important because it makes a big difference in how you can implement a solution. I have been successfully load balancing a cable and DSL connection for several months and I am very happy with how it has worked out. I am using a Linksys RV082 –

I got lucky and bought it off eBay for a great price. I have also since noticed that Linksys has a new version (RV016) that handles several WAN connections.

I am ultimately holding out for a Linux solution though. Any news out there?
