Internet Gateway Tricky Question

MajidKhan · 11-01-2011, 06:52 AM

Hi,

I have 4 DSL lines for the internet access and I have to share the internet on my LAN (almost 200 nodes). I'm planning to have a dedicated server for this task having 5 GbE ports, because each DSL modem gives out Ethernet link.
Is this possible via iptables?? and some kind of link aggregation is possible? How can I handle and performs NAT on local ip addresses given by DSL modems?? Any suggestions?

Thanks..

I really have nothing to go on, but a google search for "multiple DSL load balancing" turned up a few results that might help..

From what I read its not possible to bond the connections together for one super fast connection, but it is possible to distribute the load between the 4 connections...

Hi, what you want is called device bonding (or aggregation). Bonding multiple network devices into one. Then you can set up different priotities for the specific devices. Official kernel docs. A howto I found.

Normally one uses load balancing but you could use ip address set to ranges to route and thereby balance.
