The box will have 3 interfaces eth0 going to the Cisco 7200, eth1 (routable IPs) going to the webfarm for DMZ zone, and then eth2 will be NATed with a private LAN IP (192.168.1.x). I will be NATing over 200 clients and I know in the past this could be a problem with IPCHAINS because it would either run out of memory or start dropping connections. The webservers get about 7,000 hits a day and they won't be NATed but will be filtered with a mix of statefule and packet filtering rules. We have a Cisco PIX 525(which is just a Intel P600/512MB RAM) in place right now but I would like to move to Netfilter as it will be running on a dual P1ghz and a gig of memory. Is this possible? can Nefilter scale to this and beyond? and is there any tweaks I should know about? Thanks in advance. Mike
