Howdy, What's the proper way to firewall (using IPF) the multicast IP's (224.0.0.0/3) so that I can use OSPF on my FreeBSD 4.5-STABLE machine with the zebra port internally and over my IPSEC tunnels, while still keeping my external interface protected. I'm fairly new to this whole multicast thing, and I'd like to get this right :-) My existing configuration hits the default deny whenever ospfd tries to multicast (every 10 seconds). This is causing the following log message: warnings: OSPF: *** sendto in ospf_write failed with No route to host TIA, - Tillman -- 1. Out of clutter, find simplicity. 2. From discord, find harmony. 3. In the middle of difficulty lies opportunity. - Albert Einstein, Three rules of work To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
