I have installed PPTPd on Centos 5.6 and clients are connecting from windows XP. it was working fine , now from last 1 week My sessions are disconnecting after some time. I tried installing fresh pptpd but the issue is still there. Now i did capture PPP packets on client machines by Wireshark and got to know that when the disconnection occurs the PPP LCP protocol is showing Protocol reject messages where destination is the client IP. Any body encountered the same problem please share the solution.

Sorry for the late reply. The “IP addresses for server end of connection” in the second screenshot is also supposed to be a private IP like 192.168.1.1. If you were following this tutorial, maybe you should have manually edited /etc/pptpd.conf instead of using webmin to configure pptpd.

Once again, I apologize for the late reply.

Hi there, excellent tutorial! However, just getting a small issue that I can’t quite figure out. I’m able to connect to the VPN server fine, but once I am connected I don’t seem to be able to browse the internet at all. I double checked my iptables and they seem correct: http://pix.cm/s/2011-10-12_03-18-11.png

Also for the options.pptpd file I used Google DNS for my DNS servers, but I tried other ones as well and that didn’t change the situation.

I’m wondering if perhaps the IP address settings here might be incorrect? http://pix.cm/s/2011-10-12_03-20-18.png

If you could just point me in the right direction, that would be greatly appreciated, or at least what to look over for potential errors as I’m not being given any sort of errors and have no idea how to begin to troubleshoot this.

Thanks!!

I am no longer using PPTP. I use OpenVPN now. But when I wrote this tutorial I was using CentOS 5 and the pptpd version I was using is mentioned in the tutorial (1.3.4). i do not remember the kernel or ppp versions that I was using.

By the way, this tutorial will not work on most virtual private servers. And VPS providers will usually advertise PPTP support if it is supported by their VPSs.

@Aziz and @n0rbertt

Sorry for the later reply. Unfortunately, I have never encountered the issues that you guys mentioned and so I have no idea how to solve them.

But I do hope that by now you guys have managed to solve your problems yourselves.

Nice article, consise and too the point. Often the problem with doing things in Linux is just getting started, getting the simplest configuration and starting from there.
This artice did this, which is a good thing.
Well done.

”
