I have 1 Ubuntu 12.10 server with 1 eth0 (192.168.0.100) and it's connected to my switch. In my network I have 2 ADSL routers (192.168.0.1 & 192.168.0.101).

How I can configure my server to act as load balanced router (all PCs conected to 192.168.0.100 as gateway) to gain more bandwith or mix bandwith (2 x 4M) ?

Or there is a cheap hardware to do that like PCs -> box -> ADSL1 AND/OR ADSL2 ?

  • thanks to give me the right keywords for my search, but I only found examples on multiple Ethernet cards and not on 1 card only. Can you point me to a more specific link ? – Mike Castro Demaria Feb 27 '13 at 13:44
  • You can create multiple aliases for your network device, so it doesn't matter if you are just using one (physical) interface. http://www.cyberciti.biz/faq/linux-creating-or-adding-new-network-alias-to-a-network-card-nic/ – Henry S. Feb 27 '13 at 14:13
  • Thanks Henry, I know how create virtual interface, but I don"t know how to add a specific route on the C & B interface and use A as gateways for other PCs who will be routed using C & B dynamically. – Mike Castro Demaria Feb 27 '13 at 15:17
  • Henry : following http://www.debian-administration.org/article/377/Routing_for_multiple_uplinks ip route add default scope global \ nexthop via 192.168.0.1 dev eth0:1 weight 1 \ nexthop via 192.168.0.101 eth0:2 weight 1 Virtual IP seem not work with error message : Error: "nexthop" or end of line is expected instead of "eth0:2" – Mike Castro Demaria Feb 27 '13 at 15:49
