I will try to dig up why the broadcast addresses aren't there.

Will try this also. Does my inexperience of using stuff like tcpdump
show? No? :)

I had posed this question towards the beginning of this thread. In
particular, I was wondering if I need to have different wires for
my 2 networks. The impression I got was a lot of people have my
current physical setup. But since you're saying you shouldn't have
the same wire going from ed1 and ed2 (in my case), and if I switch to
10bT for my network rather than 10b2 (mostly), would I need 2 hubs?

Crist, I'm curious about the physical layout of your network. Can
you give me a simplified view of it? Here is my current layout from
my old message in case you didn't catch it:

[isdn]
  |___10bT___[hub] ("wire 0")
               |___10b2___[Mac]___10b2___[FreeBSD w/ 2 ethernet cards]
 ("wire 1")->  |
               |___10b2___[NeXT]___10b2___[NeXT]

I was thinking of needing a setup like this:

[isdn]
  |___10bT___[hub] ("wire 0")
               |___10b2___[FreeBSD ethernet card 1] (net 15--ed1--"wire 1")
                          [FreeBSD ethernet card 2] (net 10--ed2--"wire 2")
                             |___10b2___[Mac]___10b2___[NeXT]___10b2___[NeXT]
