It depends on how you want to set things up.

Shouldn't be required but is probably better than using Win95 
to connect.

I'm not sure about what you mean by broadcast.  If I were in you
shoes, I'd use the FreeBSD box to dial out and maintain the
connection.  After it dials, I'd have it send email to a account
you have on a fully connected computer with it's dynamic address.
When you want to telnet to a machine at home, check your email,
get the address, and telnet to the FreeBSD box.  Then telnet to
the machines on your local network from there.  This is (I think)
the simplest way to do things.  I do know of people who have set
up Linux routers where you telnet to a specific port to get a
particular machine.  I think they patched telnetd to do it.
