Hi, I'm trying to put some filters on pppd as added protection (not replacing ipfw), but they don't seem to have any effect. Here is what I have at the moment in /etc/ppp/options : pass-filter ' !(inbound && dst port 20) && !(inbound && dst port 21) && !(inbound && dst port 22) && !(inbound && dst port 80) && !(inbound && dst port 111) && !(inbound && dst port 139) && !(inbound && dst port 2049) && !(inbound && dst port 3128) && !(inbound && dst port 5801) && !(inbound && dst port 5901) && !(inbound && dst port 6001) && !(inbound && dst port 8000) && !(inbound && dst port 8001) ' I dropped my ipfw and used a couple of online firewall testers but they indicated that the ports were open so I assume my pppd filters aren't working. PPP_FILTER is in my kernel. Any help appreciated. Ian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
