ok, i know thats the way it should work fine. but reading a huge book takes a lot of time. i want to know, if ISA is "better than linux an iptables" (without discussing about the best operating system). So maybe, only if you have enough time for me, you could give a short summery about ISA and its funktionality .?..? :-) And i have to point out, that i am not a newbe in networking stuff - maybe more in formulating good english. And one question left: What doas "nix command" mean? i know "command", but "nix" in addition with "command" sounds strange for me. > Please get and throughly read a couple of books on ISA.
