Hi

I have a question related to load balancing.I have two separate internet connections with 2Mbps speed and i would like to aggregate this two connections intro one connection with 4Mbps.Is it possible to do that, to put a Linux or Unix machine as a gateway?I read some stuff to split the traffic on one side ftp,smtp.... and on the other side http,telnet... but i don't want something like this and if it is necessary to buy a special router i think it should be possible to use a simulator to do that like for Cisco "Dynagen Dynamip" or JunOS on a virtula machine.
I searched the whole internet and i didn't found any solution , but it must be possible to do that or not ?????

Thanks in advance
