Out of curiosity, have you tried FreeBSD + ipfilter (or even OpenBSD + pf, for that matter)? I've really come to appreciate ipfilter's syntax and flexibility, and it's statefulness always seemed to work better than IPFW's for me for some odd reason. Note that I mentioned statefulness. You should really, really investigate the potential useful of a stateful firewall. The massive win there is that once a connection is accepted, it gets added to a known-good list which is searched before incoming packets get sent through the filter list, and usually much more quickly. In other words, each "accept" rule will only get processed once *per connection*, rather than once *per packet*. Finally, I'm not sure of the lastest hardware recommendations, but I'd put the absolute best NICs in that machine that I could afford. Anyone know what the current king of the FreeBSD hill is? =2D-=20 Kirk Strauser In Googlis non est, ergo non est. --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQA+J6Ju5sRg+Y0CpvERAnzoAJ0Q3H1A2HbwyvA13Ylx3NMjTR5ODgCfWe+3 vfUC7ePnC1XyoMqzZRzPYFs= =HP4H -----END PGP SIGNATURE----- --=-=-=-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
