I upgraded a 4.2-RELEASE machine to RELENG_4_3 tonight. This box has 2 nics, uses ipfw and bridging to act as a firewall. I've been using this configuration with 4.2-RELEASE for ~200 days with superb results! Now with the reboot into 4.3-RELEASE (RELENG4_3) 2001-06-05, I see this message on console and in logs: Jun 6 21:20:21 xxxxxx bdg_forward drop MULTICAST PKT Jun 6 21:20:51 xxxxxx last message repeated 4 times Jun 6 21:22:51 xxxxxx last message repeated 13 times Jun 6 21:32:51 xxxxxx last message repeated 67 times Jun 6 21:42:51 xxxxxx last message repeated 66 times Jun 6 21:48:20 xxxxxx last message repeated 37 times ..etc.. Mind you, the bridging all appears to be working ok, at least from the hour or two that it's been running. This is more of an annoyance, which I was curious about. I managed to disable the log message by commenting line 462 of /usr/src/sys/net/if_ethersubr.c (1.70.2.15) and recompiling. Not the best solution, which is why I'm writing here today. My kernconf is quite basic, just these delta GENERIC: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_FORWARD options IPFIREWALL_VERBOSE_LIMIT=100 options IPFIREWALL_DEFAULT_TO_ACCEPT options DUMMYNET options BRIDGE My firewall config in /etc/rc.firewall was not altered at all between 4.2-STABLE and 4.3-RELEASE. I tried searching the mailing list archives and bug database, but didn't come up with much. Thanks for the time, anyone, who looks at this. -- Christopher Schulte Finger for PGP key, or for UNIX impaired: http://noc.schulte.org/cgi-bin/noc/finger.cgi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
