I've got an issue with the 4.3 release I just installed. Is it ok to ask questions about the release branch here? I'm using the machine as a gateway between my home LAN and the dial-up connection to my ISP. I have natd and ipfw configured for ip masquerading. This configuration seems to have broken after the update from 4.2 to 4.3, and I haven't been able to figure out the differences. I'm using rc.local for intitial configuration: /usr/local/sbin/mpd -bk /sbin/natd -interface tun0 /sbin/ipfw -f flush /sbin/ipfw add divert natd all from any to any via tun0 /sbin/ipfw add pass all from any to any As you can see, I'm using mpd for the dial-up interface instead of ppp because that's the one we got to work first. Conditions are changing, and I may go back to ppp. The divert command is apparently failing; when I execute it in a shell, I get what looks like a usage screen. The gateway machine itself connects to the internet fine, but none of the LAN machines can connect to the gateway or to the internet. "ipfw show" throws a core dump when I try to look at the current rules. Can someone give me a hint? (If I read the natd manpage correctly, the new version has a -dynamic switch that tells it to detect when the dial-up interface changes IP. That means I won't have to HUP the natd process every time the modem connects?) (Yes, I know the firewall is wide open; there are no external daemons running execpt sshd, and it's a dial-up connection, and the LAN machines are all running personal firewalls, and I just haven't gotten around to it, ok? :) -- Succeed in spite of management. ====================================================================== Robert Goff http://aisling.cc/resume/ Technical Writer/Editor, Webmaster 505-564-8959 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
