IDS has to be in the same Ethernet collision domain as the network you want to monitor. A common way to do this is to use port mirroring on a switch, or to put a hub in the traffic path. You can't do what you're asking.

Dear All<br />
<br />
I have another important question.<br />
<br />
Now I have my IDS connected to my lan.. my network is like this ...<br />
<br />
I have 20 sites(Networks) 9 of them are connected using a Fiber cable (same subnet) and the other are connected to me using one router.<br />
Can IDS in my location (site1) detects the Intrusions in other sites which connected to me by a router??<br />
i can ping any Ips in thos sites.<br />

IDS Helps

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
