I hope this is the best place to put this thread. Anyway, I've been wondering if it is possible to put snort or something similar on my wrt54g-tm router. After looking around on google for a while with mixed results, I decided I would come here and ask the security experts.

I've read tcpdump will work, but some people says it freezes up the router.

I have a web server that stays on 24/7 running ubuntu. So if I need a computer to dump log files on I could use that computer.

I don't want to get any additional hardware.
