Hi, Has anyone had any trouble (or success for that matter :-) using the builtin bridge(4) with multicast packets? I'm running 3.2-RELEASE. When I run tcpdump on a Sun that is behind the bridge, I get the following (note that both machinea and machineb are on the 'outside' of my bridge): 09:35:24.338648 truncated-ip - 14280 bytes missing!machinea.35468 > 224.2.0.1.43211: udp 28 (ttl 17, id 12534, bad cksum e3ca!) 09:35:24.378846 truncated-ip - 15300 bytes missing!machineb.38860 > 224.2.0.1.43211: udp 32 (ttl 31, id 38687, bad cksum ab27!) tcpdump from the bridge computer: 09:35:24.495187 machinea.35468 > 224.2.0.1.43211: udp 28 (ttl 17, id 63024) 09:35:24.535392 machineb.38860 > 224.2.0.1.43211: udp 32 (ttl 31, id 8087) I've set net.link.ether.bridge=1 and tried setting net.link.ether.bridge_ipfw to both 1 and 0 (I get the same result). My ipfw rule is: 65535 allow ip from any to any Any ideas? ...thnx, ...dave alden To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
