Fabian, Actually, what you're looking for is not link aggregation - link aggregation works on level 2 and creates a virtual interface with a single IP address. What you want is to have two routes to the same network (on your case, the default gateway), each one with a single IP. This configuration is known as multiwan or link balance, and involves playing with ip route.
