This page details step by step how I accomplished aggregating two separate internet connections into one, seemingly single, connection to the Internet. This “single” connection has a greater bandwidth capacity that either of the individual connections could yield. As a side affect this also nicely doubles up as a redundant connection. This method can be used for achieving link aggregation for both home and business users alike for a fraction of the cost of commercial connections / aggregation units available that do the same thing and in theory could be expanded to as many links you like however be warned, the more links there are, the more overheads there will be with tunnelling; thus potentially noticeable drops in speed.
For this demonstration I am using two Virtual Machines via VirtualBox. This enables me to experiment with without cutting my servers off from remote administration. Both machines are running Ubuntu 10.04.3 LTS (Lucid) however there is no reason this wont work for other distributions as long as you modify the steps accordingly. Read More
