Subject: IPCP-Nak doesn't do anything
Date: Wed, 12 Dec 2007 21:15:45 +0000	[thread overview]
Message-ID: <14303969.post@talk.nabble.com> (raw)


Hi,

I'm trying to get two PPP devices to work together to setup a PPP
connection.  I have control over one of them - meaning I can set whatever
options I please - but I can't control the other device, it's options are
hard-wired.

I think I've almost got them working because they pass the LCP request - ack
stage and enter the IPCP stage.  In the IPCP stage, my IPCP-Req is Ack'd, so
I'm halfway there.  Their IPCP-Req is received by me with IP-addr=0.0.0.0
and I respond with IPCP-Nak IP-addr\x192.168.20.50.  All this seems correct
to me, but then the device doesn't accept my Nak and either re-sends its
original IPCP-Req or goes back to the LCP-Req stage.  

Does any have ideas on why this could happen or something I can try?

My log is below, Thanks for reading :)
