Overall, it aims to offer many of the key features of IPSec but with a relatively lightweight footprint. Install the openvpn package, which provides both server and client mode.
Users of custom kernel should make sure to enable the tun module:. Read Kernel modules for more information. To connect to a VPN service provided by a third party, most of the following can most likely be ignored, especially regarding server setup.
One should use the provider certificates and instructions, see Category:VPN providers for examples that can be adapted to other providers. Alternatively, as of OpenVPN 2. See the OpenVPN documentation for details. OpenVPN is an extremely versatile piece of software and many configurations are possible, in fact machines can be both servers and clients. With the release of v2. The OpenVPN package comes with a collection of example configuration files for different purposes.
The sample server and client configuration files make an ideal starting point for a basic OpenVPN setup with the following features:. For more advanced configurations, please see the openvpn 8 man page and the OpenVPN documentation. If TLS with elliptic curves is used, specify dh none and ecdh-curve secpr1.
DH parameters file is not used when using elliptic curves. Starting from OpenVPN 2. Otherwise the server would fail to recognize the curve type and possibly use an incompatible one, resulting in authentication errors. See this article. One can have multiple, concurrent instances of OpenVPN running on the same box. At a minimum, the parallel servers need to be running on different ports. A simple setup directs traffic connecting in to a separate IP pool.
More advanced setups are beyond the scope of this guide. Be sure to setup the corresponding entries in the firewall, see the relevant sections in Firewall configuration. Using the options user nobody and group nobody in the configuration file makes OpenVPN drop its root privileges after establishing the connection. The downside is that upon VPN disconnect the daemon is unable to delete its set network routes again. If one wants to limit transmitting traffic without the VPN connection, then lingering routes may be considered beneficial.
It can also happen, however, that the OpenVPN server pushes updates to routes at runtime of the tunnel.If you're new to OpenVPN, you might want to skip ahead to the examples section where you will see how to construct simple VPNs on the command line without even needing a configuration file. Though all command line options are preceded by a double-leading-dash "--"this prefix can be removed when an option is placed in a configuration file.
If --config file is the only option to the openvpn command, the --config can be removed, and the command can be given as openvpn file Note that configuration files can be nested to a reasonable depth. Double quotation or single quotation characters "", '' can be used to enclose single parameters containing whitespace, and " " or ";" characters in the first column can be used to denote comments. Note that OpenVPN 2. Use a dynamic tun device.
The OpenVPN client will try to connect to a server at host:port in the order specified by the list of --remote options.
The client will move on to the next host in the list, in the event of connection failure. Note that at any given time, the OpenVPN client will at most be connected to one server. Note that since UDP is connectionless, connection failure is defined by the --ping and --ping-restart options. This could cause the client to exit with a fatal error. If --remote is unspecified, OpenVPN will listen for packets from any IP address, but will not act on those packets unless they pass all authentication tests.
This requirement for authentication is binding on all potential peers, even those from known and supposedly trusted IP addresses it is very easy to forge a source IP address on a UDP packet.
When used in TCP mode, --remote will act as a filter, rejecting connections from any host which does not match host. For example, "foo.
An OpenVPN client will try each connection profile sequentially until it achieves a successful connection. If that fails, we then try to connect to If that also fails, then try connecting through an HTTP proxy at Finally, try to connect through the same proxy to a server at These will only try IPv4 to connect to the remote host.
To use IPv6, add "6" to the protocol, as in udp6, tcp6-client, or tcp6-server. OpenVPN 2. For UDP operation, --proto udp should be specified on both peers. For TCP operation, one peer must use --proto tcp-server and the other must use --proto tcp-client.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Using my very slightly modified fork of the repo to run the server and generate the keys, I get an error when importing the keys into the Android app. My guess is that this is due to my modifications, which were intended to make the script work for the current version of Raspbian on a Pi 2. If you're getting this error then something is wrong with your public IP address.

As long as you follow the readme directions exactly then the script should do everything else that needs to be done. I'd try without the ddns first and eliminate duckdns as the problem first.

To make this happen, create a file with the Common Name of the certificate the remote office gateway uses to authenticate itself to the server I looked it up in the ipp. That file needs to contain a single setting:. Note that because we persist the DHCP lease log in ipp.
The topology subnet setting has caused some issue for me, but I finally got them resolved. The solution was to add the remote offices gateway adress to the route setting:. Thanks for the additional help will try this myself. I have one question though.
Where should this route be place on the Openvpn Server of the Openvpn client. I realize its in the Openvpn server config at first then further down you talked about placing else where. I have having some major problems. I cannot get Openvpn to route at all.
I am using dynamic public ip on both networks. I already have dynamic hosting working soi can able to connect both boxes over the internt My remote network is the I know i have to open port on both boxes to point to the Openvpn server and Client respectively. Can you please assist in my endeavor. Thanks in advance. Thanks for your article. This helped me out on solving the routing issue I spent too many days on. You are commenting using your WordPress.

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. I've got an OpenVPN client that isn't connecting to the vpn server. I've pasted the full log below, but in particular, I'm getting these issues with the route:. There are many clients with the same client config that are connecting just fine.
This client and a few others was connected, lost its connection due to the system time becoming too far out of sync I believehas since synced the system time, but is now still unable to connect. Usually, restarting the system fixes the issue. So it doesn't appear to be an issue with the VPN configuration but something with the client system. I don't really know enough to understand the route issues or fix them.
I do need to deal with recovering from the time sync issue, but for now, why can't I manually start a VPN connection from this client? What would cause OpenVPN to now need a gateway parameter?
The subnet topology is generally a better option for newer clients. When you use the topology subnet it will automatically perform a push "route-gateway There are currently 62 connected clients. That alone sounds promising. Can you point me to options that increase the max number of hosts? Ah there is your explanation. Your server So You have two options to fix this, you can change your subnet size in the server statement, and make your subnet larger.
This may mean you need to update any routing tables on other devices in your network, and change firewall rules. Or the probably easier solution is to switch to the topology subnet. This makes your not use this psuedo point-to-point topology and makes it basically act like an ethernet switch. The only reason should stick with the older topology is if you have really old clients connecting. Sign up to join this community. The best answers are voted up and rise to the top.

Your server doesn't seem to be pushing an IP address to the client. This is weird, because it should be pushing one, given the configuration you provided.
With server Are there other computers already connected to this VPN? No, I didn't change that. Does the topology subnet option mentioned in the answer below fix both of these issues the max hosts and the push? Active Oldest Votes. It shouldn't be required, but I suggest adding topology subnet on the server.
