I'd read that embedded pfsense 1.2.3 was going to have some package support but I was pleasantly surprised to see snort!

I've always understood Snort on embedded to be a bad idea -- certainly for the obvious reasons (limited embedded CPU power), but also due to the write limitations of flash memory. I might venture that my IDS/IPS needs are few. Essentially All I want is to know (and respond) if anyone's beating on my SSH & VPN ports. Hopefully I would also be able to blacklist IP's that are brute-forcing my SIP ports.

I haven't yet played with snort, but I'm wondering if it's reasonable to run it on an embedded Soekris 5501-70. We have a meager 6 megabit symmetric DIA pipe. Is it within scope of an embedded system for the 'lite' IDS/IPS needs I've described?

Pontification welcome!
