However, this is only a problem with packets in response to a broadcast packet. In my limited understanding I find the behaviour a bit bizarre. ICMP pings will work from a remote windoze machine tagged as VLAN 10 as the packets pass into the switch until it's ARP entry for the freebsd box expires or I deliberately delete it. The arp request shows up at the FreeBSD machine, but the arp-reply back to the Windows machine doesn't get there. Can I trust tcpdump's output? It gives every indication there is a well formed arp-reply packet going back with the correct tag. > -- > Markko > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
