I've run IPCop on several home networks and been pleased with the  
results.  Lately I've been thinking about giving pfSense a try as  
well.    Mainly, it looks like the web GUI in pfSense is a bit nicer  
to use, but learning a bit more BSD would be a plus.  I was thinking  
of installing that on a little soekris box to get rid of the noise of  
an old workstation running the firewall.

Anyone who's used both IPCop and pfSense care to offer a comparison?   
Anyone run it on a small embedded device like the Soekris I linked to?

Regarding Snort : I ran that on an IPCop instance for a while, but  
ended up shutting it down because of a lack of analysis tools.  It  
generated this massive log file, and IPCop provided no way to look at  
it except by manually trolling the log.  I looked into adding mysql to  
IPCop (since snort can also log to a database), and then you can use  
Base to examine the logs.  Adding mysql, recompiling snort, etc, etc,  
inside the IPCop distro proved to be a bit more than I was willing to  
invest the time in.

Lisa, I'd be interested to know how you use snort in these conditions?
