I will use almost no logging. My ruleset will be rather short: 500-600 lines, with SNAT/DNAT in about 5% of these rules. Only ipv4 will be used in this firewall setup. I expect substained rates of 300-400 megabits on EACH gigabit interface, with gigabit peaks. I also expect 40.000-50.000 concurrent connections (mainly http/smtp/dns traffic). I also expect 500-600 megabits of NATed traffic (to & from internet) Which gigabit ethernet card is more suitable for high perfomance filtering? Any special advice about linux distro/ kernel tuning? Thank you for your support
