Hmm. What do the boot messages for each machine show is going on?
You can find them in /kern/msgbuf (if you have /kern mounted).

What does netstat -r say?

My first concern is that you might have the routing messed up (if you
ran ppp and tried to run ethernet in the same boot).

Forgive me if you've set everything up right already.

I've done this before, and here's what I did:

The big thing is that you must give each *interface* its own IP
address. I have pokey, the IIsi, and banana, the SE/30.

/etc/hosts (on each)

10.0.0.1	pokey
10.0.0.2	pokey-ppp
10.0.0.3	banana-ppp
10.0.0.4	banana

Pokey:
ifconfig ae0 inet 10.0.0.1 netmask 255.255.0.0

Banana:
ifconfig ae0 inet 10.0.0.4 netmask 255.255.0.0
route add default 10.0.0.1

and the ppp connection's set up so that banana gets 10.0.0.3 and pokey gets
10.0.0.2.

What was your setup?

Take care,

Bill
