Many commercial sites do use FWTK. It is a firewall toolkit, though, and not a firewall. IIRC, the license prohibits commercial re-distribution, not commercial use. Many other sites use ipchains. Packet filtering only makes me uneasy, tough. Apache, Squid, BIND, and Sendmail can all be used as proxies, although again the sheer complexity of code in, specifically, sendmail may make it less desirable as a proxy. -- Joe Yao jsdyat_private - Joseph S.
