Hi, i'm having troubles detecting traffic, my network is more or less: DMZ | |------- LAN 1 (segment 191.168.1.x) INTERNET ---- GW --(1)---GW-- |-------- LAN 2 (segment 191.168.2.x) segement X | . | . |------- LAN N (segment 191.168.n.x) I put my sensor on (1) a segment x (192.x.x.x) and i would like to catch all traffic from every LAN (segment), but i'm not logging all alerts, i mean, suppously i'm on the fist segment and i ping a server on the DMZ i can't see the traffic neither in sniffer mode, so the question is: Why i'm not logging alerts from other segments that aren't in the same segment where i put my sensor?.. What can i do to log alerts?
Snort, as well as all other NIDS software, are more dependent on actuall hardware setup of the network then the logical design. You have not told us how you get your snort to collect data (hub/switch/tap/inline) and how the segments you want to monitor is connected to the network. If you are using switches in your network you must make sure that they support SPAN port or mirror ports (each vendor seems to invent their own word for it). If you are using hubs, make sure that they are true hubs and not switching hubs (if it says "10/100 Mbit hub" on the box it's almost for certain a switching hub). Please let us know the physical setup of your network and we can help you troubleshoot your problem.
