I'm usually not very good at recommending books, i mostly learn by reading reference manuals, standard documents, and source code. It is mere chance that i know this one. :-) I mentioned it to show that the strength of two-tier firewalls has been well-established in standard textbooks for a long time. There may be books out there on the topic that are newer than Elizabeth Zwicky's and of similar quality, i don't rightly know. Yours, Ingo
