Subject: WACKY CIPE ISSUE -- MORE (TCPDUMP)
From: SD <sdtechnet,AT,yahoo,DOT,com>
Date: Wed, 12 Jun 2002 17:24:31 +0200

What I can tell by looking at this is the Machine A
seems to work.  The cipcb1 interface comes up and
actually pings to Machine C, and Machine C gets it. 
Due to the fact Machine C's cipcb0 interface does not
initialize, it can't do anything with them.  Any
thoughts on what is going on?  Machine C has a DSL
connection with a Cisco 678 setup as PPP and a nat
entry to forward all ports to the 10.0.0.2 address
(firewall/CIPE box)

Thanks,
