Load balance between ADSL lines

10 Jul 2003

      Hi everybody!

One of my customers have asked me to set a system to use four 2Mb ADSL lines
as a single 8 Mb one. My intention is to configure a Linux server to perform
the task, but I haven't found any software yet (no linux distribution seems
to support this feature by itself). The system should behave similar to the
NLB utility from Windows 2000 server. There are routers from Cisco that
could perform this task, but they are a little expensive :-(

Here's a little diagram of what I'm trying to do:

#######         ##########
# LAN ########### Linux  #################### ADSL router 1
#######         # server #     #     #    #
                ##########     #     #    ### ADSL router 2
                               #     #
                               #     ######## ADSL router 3
                               #
                               ############## ADSL router 4

The linux server should interconnect the local network and the four ADSL
routers, performing load balance between them. Any idea is welcome :-)

Thanks in advance. Greetings ;-)
