where can I find a detailed step-by-step howto for making a linux gateway with the following features :
1- internal pppoe network with freeradius authentication .
2- dialup admin script to control users bandwidth and other things.
3- the ability to "merge" more than 1interface (like 3 internet gateways from 3 different ISPs) into the same server so I double my server speed
thank you for answer
