PPTP VPN Pix Droid phone

[budmiller]

I have been trying to set up a PPTP VPN between a Droid phone and a Pix running 6.3.5 code.  As far as I can tell the configuration is correct and I can open the pptp vpn fine from my laptop however the Droid refuses to connect.  Here is the relevant configuration.

vpdn group droid accept dialin pptp

vpdn group droid ppp authentication pap

vpdn group droid ppp authentication chap

vpdn group droid ppp authentication mschap

vpdn group droid client configuration address local vpnpool2

vpdn group droid pptp echo 60

vpdn group droid client authentication local

vpdn group droid username ****** password ******

I have turned on the following debugs:

debug ppp negotiation

debug ppp io

debug ppp upap

debug ppp chap

debug ppp error

debug ppp uauth

debug vpdn event

debug vpdn error

debug vpdn packet

I have narrowed the problem down to the following message but I am uncertain as what it means:

If I am reading this correctly is the Pix rejecting the proposed configuration from the Droid phone? 

Any suggestions or help would be greatly appreciated.

I am experiencing the exact same issue.  We are getting this response with Debugs on the PIX 6.3

Any help would be appreciated.

Hello chsparrow,

Recently I had the user update the pptp app on the Droid and then the pptp tunnel worked fine.  I made no config changes on the Pix so I think it was something to do with the pptp application on the phone.

Thanks,

Bud
