Well I can't write your test plan for you, but in general you'll need: 1) Some pcap files of the type of traffic you want to test with. Basically pcap's of "real world traffic" or whatever meets your test criteria needs. Might want to throw in some malicious traffic in there too. 2) A way to monitor the performance of the firewall. SNMP is probably a good generic solution, but your firewall might have something better. 3) Two boxes- on a web server the other a client. Put one on either side of the firewall and use them to verify the firewall is still properly passing traffic. There's plenty of web performance tools on Freshmeat.net which would give you information about latency, and other performance metrics. Comparing performance numbers w/ and w/o the firewall as well as w/ and w/o load would tell you the effect the firewall has on network performance. Then use tcpreplay's feature to send traffic at different speeds. You can use packets/sec or Mbps for example. This is where the new v3.3.0 code can really help. Be sure to read the online manual for more info: http://tcpreplay.synfin.net/trac/wiki/tcpreplay#ChoosingaTimingMethod Anyways, it would be great that once you've written your test plan if you could share it with others. I'm sure a lot of people would find it useful. Also, if you can, share your pcap files on openpacket.org! -- Aaron Turner http://synfin.net/ http://tcpreplay.synfin.net/ - Pcap editing & replay tools for Unix They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
