[pptp-server] Problems logging into PopTop

[Andy Ennamorato]

Poptop gurus,

I recently setup PopTop 1.1.2 on a Linux RedHat 6.2, Kernel 2.2.14 machine.
I have ppp 2.3.11 and use an
ADSL connection to access the Internet. The Linux box acts as a
firewall/router for a Win98 machine sitting behind it,
but I "opened" the firewall to test the VPN/PopTop connection.

When I try to connect from the Win98 machine from behind the firewall
(going out, then coming back in using the
Linux box's external IP address), the Win98 client will say "Username and
password verified...", writes approximately
300 bytes, then disconnects. If I try again, after that, it doesn't even
make the connection.

I believe that I just don't have the right setup with the chap-secrets and
the /etc/ppp/options files. When I look at the logs
(pptp.log and /var/log/messages), I noticed this error:
>Jan 15 18:22:54 yoyodyne pppd[1215]: Peer is not authorized to use remote
address 192.168.1.70
>Jan 15 18:22:54 yoyodyne pppd[1215]: sent [IPCP TermReq id=0x3
"Unauthorized remote IP address"]

I've searched through the archive and through some of the old messages I've
seen go by on the list, but couldn't
quite find an answer.

Here's a copy of my options file (/etc/ppp/options - is it advisable to use
a options.pptp type file instead?):

lock
debug

Here's the /etc/pptpd.conf file:

speed 115200
debug
localip 192.168.1.80-89
remoteip 192.168.1.70-79

Here's the chap-secrets file:

# Secrets for authentication using CHAP
# client        server  secret                   IP addresses
guest   *       XXXXX   *
andy    *       XXXX    *
"anjoju"        *       "XXXXX"

The last line in the chap-secrets file is for the ADSL connection. Does
PopTop use " "'s around the username/secret, or is it fine
with just spaces and tabs to delimit the fields?

Finally, here are portions of the /var/log and /var/log/pptpd.log files,
relevent to the error I'm getting. I've tried following the
RedHat-PoPToP.txt file and using the FAQ on http://poptop.lineo.com, but
still no luck. Could someone post their chap-secrets/pptpd.conf files, I'm
sure I'm missing something stupid.

Thanks in advance,
