I currently have a DSL line and a FreeBSD firewall/gateway (dual homed). It has one internal IP address and 5 external IP address (one "real" ip and 4 alaises on same external nic). What I want to do is montior and record (to log) all incoming/outging connection (just source ip/dest ip/port). If someone connects to my web server it should log what ip accessed it, the time, which ip (web server runs on 2 external ip address) and the port. Also if someone does a port scan against the box I should be able to tell it is a port scan (since one ip address would be opening up a bunch of ports). Right now I don't care what data is being sent/received, just what connections are being made (and the details about those connections). Any suggestions?
