The topology is insane. Don't worry about using all of the ports on the ADSL router -- it's only got 4 ports because cheap ethernet switch ASICs come with 4 ports and a uplink. Without a great deal of hassle you'll end up with all of your traffic going down one of the four Server-Router links, since all those links will necessarily be in the same subnet. To achieve what you want to do: - configure the ADSL router as a ADSL bridge. - connect the ADSL router to the Server (eth0). - connect the Switch to the Server (eth1). - connect the Hub to the Switch (might need a crossover cable, or to activate a MDI-X button) - connect all the PCs to the switch and hub. Those connected to the switch will have better performance. - configure NAT on the Server - configure firewall on the Server - configure DHCP and DDNS to allocate IP addresses - configure fprobe-ulog (or similar) to generate NetFlow (IP traffic) records from NAT - configure flow-tools to collect and report flow information. - configure ntop is you want something more interactive. > Do people know of any good Linux compatible multiport NICs I can use ? At ADSL rates, anything will do. Otherwise, the Intel Pro/1000 Server MT works best with Linux. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
