Hi all! I''ve the following config: [LAN] - [big router] - [dsl router] - [internet] Big router is a dedicated computer running linux, dsl router is a small device running linux embedded (busybox) and connected to the internet via pppoa. Both routers are connected together via ethernet. I want to reduce as much as possible the load in the dsl router, so I''d like the big router to do NAT. How should I configure both routers? Thank you very much for your help! Eduardo Fernández
