Hallo, Artur, Du meintest am 21.01.13: > Can you please > make full filter with test, I know that i maybe asking too much but I > struggle to do this quite a while :( Sorry - I have enough other work to do. > and what is schueler It's the german word for "pupil". > with complete version of filter I would understand how this work, > exactly with time I started to get problems No - you should try to understand how "squid" works. Perhaps you know how a potato harvester works: it sorts for size, and it sorts out all particles which ar not potatos (a bit simplified). small potatoes: sort it out into the basket for "small" - ready no potato: sort it out to "garbage" - ready bigger potatos: go on to the next station And then you should study how and when acls are AND-combined or OR- combined. Viele Gruesse! Helmut
