I did't manage to resolve my issue. On all members of bridge0, except
sis0 (so sis1, sis2, sis3) I cannot use dhcp (Ethernet broadcast).
You can find my pcap files, which I mentioned in my previous email at
location ref#1. I've also uploaded there `ifconfig -A' output of that
router. My all emails are at ref#2 if you need to re-read what I've
wrote before in this thread.
