Re: ipfw denies everything and i can open websites?
I'm sorry, (don't laugh too hard) i had a litle startup script that read: ipfw disable firewall, i put that there before i had actually made my firewall rules... Once i removed it it turned out my rules weren't as decent as i thought, but now they work! And i was being so happy that i had made such a nice firewall :( I really thought my firewall was on because it loaded the rules and so... thanks anyway :) -jurjen ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

hello, could you show /etc/rc.conf and /etc/rc.firewall files?
