Help setting up PPTP VPN server

Hey guys,

I'm setting up a pptp vpn server but I haven't been very successful and after hours of googling for an answer I don't know what else to do so a bit of help would be very welcome.

/etc/pptpd.conf

option    /etc/ppp/pptpd-options
noipparam
logwtmp
localip    192.168.10.50
remoteip 192.168.10.51-61

/etc/ppp/pptpd/options

name compus
auth
require-mschap
require-mschap-v2
require-mppe
require-mppe-128
nomppe-stateful
ms-dns 192.168.10.1
netmask 255.255.255.0
nodefaultroute
proxyarp
lock

/etc/ppp/chap-secrets

myuser        compus    password    *

/var/log/daemon.log

Dec 22 10:04:10 proliant pptpd[10968]: CTRL: Client 123.243.x.xx control connection started
Dec 22 10:04:11 proliant pptpd[10968]: CTRL: Starting call (launching pppd, opening GRE)
Dec 22 10:04:11 proliant pptpd[10968]: GRE: read(fd=10,buffer=610c60,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs
Dec 22 10:04:11 proliant pptpd[10968]: CTRL: PTY read or GRE write failed (pty,gre)=(10,11)
Dec 22 10:04:11 proliant pptpd[10968]: CTRL: Reaping child PPP[10969]
Dec 22 10:04:11 proliant pptpd[10968]: CTRL: Client 123.243.x.xx control connection finished

Thanks a lot.

Hi there,

I may be wrong but it looks like GRE packet get lost on their way to your your server. I would check the following points:
- if your VPN server behind a router, check if GRE packet are correctly redirected to your VPN server
- have you configured the firewall of the VPN server to allow incoming GRE packet ?

Edit: Did not see the first post was that old...

Re: Help setting up PPTP VPN server

had the same issue for some time, until I came across this (Dutch) site which states that you should put the password between quotes, so try

myuser        compus    'password'    *

instead of

myuser        compus    password    *

in your /etc/ppp/chap-secrets. Works fine with me now.

Re: Help setting up PPTP VPN server

All right then, the OP is almost two years old now so let's put this one to its deserved rest.

Closing.
