Hello All; I recently installed Snort on an "IDS bridge" using OpenBSD.
So the "IDS bridge" is a box with -- what? -- two NIC's? Are the NIC's assigned IP addresses, or are they address-less? If this is the case, you may want to check the list archives, and the FAQ's 3.1 and 3.2... How do you have $HOME_NET and $EXTERNAL_NET set?
The setup is a cable modem. The "IDS bridge" is between the cable modem and the NAT box (another openbsd box). The NAT box is dynamically assigned an IP address in the 68.48.xxx.xxx range by the cable company. The internal network is a 192.168.0.0/24 network.
If you're getting a dynamically-assigned IP address back on the NAT box, /* somehow I'm having a hard time picturing this: the modem and the "IDS bridge" are just acting as though they're wire: packets just pass through with their IP addresses unexamined? */ how do you account for that relative to $HOME_NET? Do you have some equivalent to: var HOME_NET $ppp0_ADDRESS <snippage> - John -- "Cowardly refusing to create an empty archive."
