That is, customer A *wants* to see all the Netbios broadcasts from customers
B, C and D, and vice versa? Oh well. I can't help you really, except perhaps

Proxy-ARP is easy enough in FreeBSD: there are net-mgmt/choparp and net/arpd
in ports (I have used the former, not the latter) and `arp pub`. However
that's a long way removed from a bridge which rewrites packets - a sort of
layer 2 NAT...
