Re: how to determine whether a firewall is stateful or just a simple packet filter?

["Daniel.Deremiah" <dandy () shadowware com>]

Use a packet generator to send packets with syn-ack flags set.  I believe
nmap and hping both do this.  Just sniff on the other side to see if the
packets make it through.  If they don't the FW is stateful.  This is
probably over simplified, but is a quick way to check.
