Hi, maybe you are right. But setting up a second firewall makes me feel better ;-) Anyway. Thanks for your answer.

In your case this is the DSL router. NAT is not an option as you only have one official IP. Masquerading has to be done on the device with the official IP which is your DSL router. So there is no point masquerading a second time on a second firewall. What do you want to achieve with the linux firewall? Sticking to the DSL router and setting up a second firewall will make things very complicate.
