New project on Ubuntu Server - Need help!!!

[coyoty]

Hi all

A few days ago i was assigned with a new project.

The project is to setup a corporate server that will bond 5 pci lan cards into one! The scope is to connect 5 ADSL routers and compine the speeds of all of them.

So i would have 5 routers each 2mbit ADSL would result on a 10mbit connection.

The problem is not only that.

Because this is a corporate network the server MUST also act as a router. This is necessary because people are remotely connecting from e.g. their homes to the network.

Can anyone tell me if this can be done with a Linux server or it is not feasilbe at all?

Thank you all for reading!

I'm pretty sure you can't just combine 5 connections to make them one large connection, but I could be wrong.

I think that i can according to this:

this article refers for a dual nic

Welcome to the forums!

I've usually heard the procedure referred to as "teaming", but I'm not sure how many NICs can be combined, or if there is a theoretical limit. You can do some googling for network teaming to get some guides and additional information that might help.

What I meant to say is, you aren't going to get a 10mbps connection out of it. If you combine them together, you will get some load balancing but it won't be like having a 10mbps connection.

You can bond the ethernet cards for use on your LAN, but each ADSL modem will have its own external IP address, so you might be able to get some fraction of their total bandwidth for out-going packets, but I don't think it will work for incoming ones. It may be possible for your ISP to bond them into the same IP address that is visible to the internet, but that's up to them. AFAIK, there is nothing you can do at your end to accomplish that.
