OpenBSD has a fix for an annoying problem: http://www.openbsd.org/cgi-bin/cvsweb/src/usr.sbin/ftp-proxy/ftp-proxy.c.diff?r1=1.17;r2=1.18;f=h >How-To-Repeat: transfer files via FTP from a client behind a pf ruleset with NAT and ftp-proxy running. Sometimes, the ftp server will send a "221 Bye" packet and the client will never see the 'bye', but will only see a tcp disconnect.
