[pptp-server] PPTPd with Samba on kernel 2.4.2-2 RH71 IP routing issue

[Chris Coulthurst]

I would appreciate any help from anyone who has a clue of what to do to
make this thing work for me.  Here is my setup:

RH 7.1 virgin install with ppp-2.4.0-2 RPM
PPTP version 1.0.1
A full Class-C of internet addressable IPs (/24 if you will)
Samba 2.0.7 (yes, the redhat included one, hope this okay)

The Samba setup aside for the moment, I have configured pptpd.conf,
chap-secrets, and options to allow me to "at least" log in from a
win98SE client.  I gave static addresses in the chap-secrets to
hopefully simplify troubleshooting.

Here's the deal:  I can ping the VPN client on my home cable
modem-connected windows client once the VPN is established, and I can
ping the VPN server (although it doesn't appear to run through the
tunnel, it just goes out the default route from @home.  I cannot,
however, ping any other VPN-connected computers from the windows
client.  I can ping everything from inside the linux box VPN server
though.

Is this a routing issue?  Is it an IP forwarding issue?

I am not using the MSCHAP2 patches yet, since I just wanted to see that
this could be done reliably.  Once I get past this hurdle I have to
figure out how to get Samba to be the master browser for the workgroup.

Any ideas from anywhere?

Thanks.
