William, I don't know how difficult it would be to add awareness of PPOE to Snort. Though, I do believe that each version adds more protocols... maybe someone out there knows whether or not this is being considered. Not being a C coder I can only speculate on how easy or hard it would be to add support for PPOE to Snort. I still think that the way to go is to get a DSL modem that strips the PPP encapsulation from the packet and sends regular Ethernet frames to your PC, but maybe writing a PPPOE handler is a personal scratch for you to itch, so by all means give it a whirl. Performance... whizbang. Snort (for me) hasn't had any trouble sniffing high-speed networks. The trick is to use only the rules that you really need. If you're not running the Chameleon server, for example, there's really no need to use rules that check for the Chameleon SMTP overflow attack.

William, It looks like it is working, just doesn't know how to decode the protocol: OTHER: 2009 (99.851%) Are you using a DSL modem? It may be possible to exchange your DSL modem for one that has a bona-fide Ethernet connection in it.
I haven't look the snort source code yet, but it may be possible to implement pppoe desencapsulation like does ethereal ... Do you think that is a hard task ? What about snort performance ?
