The exact logs looked like: Jun 20 07:15:14 xxx pppd: Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded. Our Support Engineers started troubleshooting by checking the logs at /var/log/syslog and found that the ppp_generic kernel module was missing. For instance, in an Ubuntu server with Natty 11.04 version, customer could not setup PPTP. Similarly, missing PPTP module can also create problems with PPTP based VPN. For this, we executed the commands as root user on the server: modprobe ip_tables Here, to fix the problem, our Support Engineers had to enable the module ip_tables. Perhaps iptables or your kernel needs to be upgraded. Iptables v1.4.7: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) But, while configuring the firewall, he got the following error. He was trying to setup his own VPN with PPTP. Recently, a customer came up with a request to fix PPTP error. Now, the PPTP server is running on the server, listening to the connections.ДЄlthough, the steps look pretty straight forward, we often see customers experiencing problems while enabling PPTP. For this, we setup iptables rule that restricts TCP connection to VPN port.ДЇinally, its time to start the PPTP server using the command: /etc/init.d/pptpd restart Again, this will hide the private network from the outside world.ДЄdditionally, our Dedicated Engineers ensure security by restricting the servers that can connect to the PPTP server. This will link the virtual private network with the Internet. iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE To make PPTP clients talk to each other, we add the following rules to the firewall. To enable it, our Dedicated Engineers edit the file /etc/nf and add the following line: _forward = 1ДЇurther, we make the changes active by running sysctl -p For this, we need to setup IP forwarding. Now, for PPTP to work correctly, we need to forward packets between public IP and private IPs. The format to add a VPN user in /etc/ppp/chap-secrets file is ДЇor example, a user entry will be like: user1 pptpd user1-password * To setup authentication for PPTP, we add users and their passwords in the file /etc/ppp/chap-secrets. This will enable the google nameservers in the configuration. To set DNS, we add the following entries in the file /etc/ppp/pptpd-options. VPN clients use this configuration while connecting to the PPTP server. localip 192.168.0.1ДЄgain, we choose the range as per the customer requirement too.ДЄs the next step, we configure DNS servers. For example, to set the PPTP server IP as 192.168.0.1 and the VPN IP range for clients as 192.168.0.100 to 192.168.0.200, we add the following entries. Here, our Dedicated Engineers add the server IP and client IP at the end of the file. Then, we configure the pptpd by editing the /etc/nf file. This will fetch all the necessary packages and make PPTP server readily available.

To do this, we use the apt-get command: apt-get install pptpd LetвЂ™s now see how our Support Engineers install PPTP server on Ubuntu.ДЇirstly, we have to install pptp server.

And, it involves a series of steps to setup the PPTP server. Till now, we had a look at the reasons for using PPTP server. However, to overcome the problems of low security standards in PPTP implementation, we always recommend customers to include additional security settings. ThatвЂ™s why, PPTP remains aВ popular network protocolВ especially on personal computers. Additionally, it is readily compatible with most server types including Microsoft Windows. Today, weвЂ™ll see how our VPN Engineers install PPTP server in Ubuntu server and fix common errors with it.Д«efore proceeding further, letвЂ™s see why many people still prefer to use PPTP for VPN remote access over the Internet. And, to enable it, we need to install PPTP server.ДЄt Bobcares, we often get requests from customers to install PPTP server in Linux servers as part of our Managed VPN Services. Virtual private network is great way to maintain privacy of user data.ДЄlthough there are many ways to setup VPN, PPTP aka Point to Point Tunneling Protocol is still a popular choice.
