Doh,
Missed the hub part. So I guess that makes my earlier reply completely null n void and out there as it were.
Thanks for pionting out my ignorance ;D
Well running personal firewall and blackice is pretty decent. I personally would swap to Zonealarm Pro much better product and it does support NAT (network address translation) it runs about 45 bucks or so american. The free version only supports one computer.
Blackice is only good for reporting what's going on that's it.
Other than that I apologize profusely for giving out bad info there
I'll do better next time, promise
