You need to tell us just what you are trying to accomplish and
what you have running on the 3.3 system. I'm not clear on
what you want to do.

Please explain why you "*have*" to use 95 to dial your ISP.
   This is not usually the case with any ISP I've dealt with.

Are you using userland PPP or kernel PPP? Userland PPP uses
   the tun0 interface to connect to the internal networking in
   FreeBSD, so you need it. If you are using the kernel PPP,
   it's ppp0.

What does the ep0 interface connect to?

Are you running Samba on the 3.3 box? What are you tring
   to accomplish? Are you just wanting to telnet or ftp into
   it from the 95 box, or are you wanting to do file sharing
   with M$ networking? If so, you need Samba to do M$ networking.

Yes, you can have both interfaces running at the same time by
  netmasking them properly.

So, please give us some info!  My first take on this is that
you have the cart and horse reversed. The usual way to set this
up is to use the userland PPP on FreeBSD in the auto-dial mode
to set up a PPP to your ISP, then use the ep0 interface to
set up a LAN connection to your 95 boxes via their ethernet
interface cards. Then you can turn on address translation
on the PPP and the 95 box will look like it's directly on the
internet. This is a common setup for small businesses with
Windows computers and a FreeBSD box serviing as a gateway
and auto dialup.
