I have created a VPN without problems and I can connect, but I cannot browse the web on my Windows machine. I checked and for some reason the VPN does not allocate a Gateway… could that be the issue?

On my iPhone I can browse through the VPN with no problem.

@Justin

Sorry, I have no idea what might be causing the issues you are having. You should try connecting to the VPN using a different computer and from a different network and if you see that you are still having the same issues, then the problem is most likely with the server. If not, then it could be a problem with your client computer or network.

@Fen

Virtual private server’s usually have many things disabled that are required for pptp, which is why others have had problems with VPSs too.

Anyway, I am glad you found this tutorial useful.

I also get the 619 error when trying to connect using Win XP. I installed the Poptop on VPS server (CentOS 5) using this guide. It seems that there are always issues on VPS servers.

Then I installed poptop on normal CentOS (not using CentOS) and I didn’t have any problems. It works like a charm.

Thanks, it is great tutorial.

Hi Anindya

It was a great guide you posted on configuring a vpn server, But I am having few issues. 1 is it takes sometime to connect, 2nd is if i am able to connect i am able to browse for like 5 minutes, and then i loose connectivity. Any ideas as to what might be causing this?

Thanks

APF just controls iptables, so the iptables rules listed on this page should work fine for you. Also, you can put the iptables rules in the /etc/apf/postroute.rules file and APF will execute them automatically when it starts.

Any idea on how to configure APF to allow pptpd to run?

Try removing pptpd and installing the latest version, that is version 1.3.4. Here are download links for both 32 bit and 64 bit rpms. http://poptop.sourceforge.net/yum/stable/rhel5/x86_64/pptpd-1.3.4-1.rhel5.1.x86_64.rpm http://poptop.sourceforge.net/yum/stable/rhel5/i386/pptpd-1.3.4-1.rhel5.1.i386.rpm
