Is anyone using (and/or has anyone found compromises in) either one of these? If so, what's the diagnosis? Are they secure enough to protect a box for web services (on one network) and also my LAN with a second NIC? Or would I be casting my pearls?

If it is safe, I'll yank the FreeBSD gateway I'm using now and set it up for another project that I'm wanting to experiment with (DNS Services on OpenBSD). If not, I'll have to cough up the green and get another system (which I'd rather not do because this is only a temporary project ... probably won't last more than four months or so).

Any thoughts on this? I'm just trying not to learn things the "too hard" way.
