Strange client IP change on a VPN connection(pptp - poptop).txt
I installed a pptpd (poptop) server on a Debian system only for authenticating the users from my network to the server, to provide internet access to them.
At first the VPN connections seems to work fine, also the Internet access through it.
I tested the VPN on a Windows XP client, and from time to time I see that the Internet connections stops. When I look at the connection status I observe that the IP of the client had changed in the IP of the server. If I close the connection and then connect again to the VPN, everything goes back to normal.
The second problem is that I can enter into the VPN with any user and any password, although in chap-secrets file there are passwords set for the users.
A suggestion to help me out in this situation would be wellcome
Thank you in advance!
My settings are:
# cat pptpd.conf
#ppp /usr/sbin/pppd
option /etc/ppp/pptpd-options
debug
# stimeout 10
#noipparam
logwtmp
#bcrelay eth1
localip 10.168.109.1
remoteip 10.168.109.1-255

On the Windows client in the Security tab of the connection settings I dissabled the "required data encription"checkbox.
