Hi people !!! This time I want to know your opinion about iptables vs. Cisco PIX....where would you use each of them ???? Is it the same using iptables or PIX in big corporations with heavy Internet traffic ???? Which is considered the "best" and why ??? I use iptables since a long time, but my network is under 50 workstations. Thanks for your comments, they're welcome. At last, I suggest the tutorial from Jose Negreira at www.iptableslinux.com, it's really good for persons who start into iptables world. Thnking in advance, Alejandro
