Is SSL VPN the same as OpenVPN?
SSL VPN is designed to provide a firewall-like security for your network by requiring a client to authenticate with a certificate before gaining access.
OpenVPN (and most other VPN protocols) are designed to allow full-duplex communication between a client and a server, which may require the client to authenticate with a certificate to gain access to the network. OpenVPN is an open source project, so it's easy to find out what the differences are. For example, this site has a good overview of the differences between SSL VPN and OpenVPN.
As an alternative to the above suggestions, I recommend using the OpenVPN client/server setup. It's free and it works well, but if you want the extra features that SSL VPN offers (eg dynamic IP addresses, tunnelling), then go for SSL VPN.
The OpenVPN setup is basically a "wrapper" around the OpenVPN protocol. If you don't need any of the extra features, you should be able to just use the OpenVPN protocol and the OpenVPN wrapper.
Does OpenVPN support SSL VPN?
Short Answer.
You can establish an SSL VPN with any version of OpenVPN configured with the OpenVPN GUI. If you need to specify IP options and other network settings at configuration time, use the XML text files that the user manual or the command line tool produces. The following two configurations are examples of an OpenVPN that you can create by using one of these methods. The output shows just enough information so you can get going quickly: XML Configuration.
Command Line Configuration. # ./openvpn --help /usr/local/openvpn-2.4/share/doc/openvpn/examples/config-files/configFile /usr/local/openvpn-2.4/etc/openvpn/easy/bunnyServer.conf #!/bin/sh # # @config.txt # # Sample config file. Use either of the scripts # # ./openvpn --generate-config --script - # or # # cat sample.conf & # # and then # # ./openvpn --load-config /tmp/config.ovpn & # on your Linux box to begin your initial run. For example, # # cat config.txt cat sample.conf # for OpenVPN 2.x or # ./openvpn --help sample.conf # for OpenVPN 1.

What is an SSL VPN? SSL VPNs encrypt the data being exchanged between you and your VPN server, so that third parties are not able to see the data. They also prevent your web traffic from being logged on that third party server. This is called private network protection. Your Internet activity remains private, even though you access it over the Internet.
What is OpenVPN? An open source VPN technology. By its very nature, it is highly customizable and works great for small businesses, which are looking for VPN services that are easy to use and offer secure and highly-customized solutions. There are a few other benefits to OpenVPN too. You can choose how many simultaneous connections it will allow; you can also easily get a second OpenVPN configuration and use it for other networks or devices on the internet.
OpenVPN Pros. Easy to set up. Customizable and modifiable. Low start-up cost, making them easier to budget. Supporting multiple platforms like Windows, Mac, Android, and Linux. OpenVPN Cons. Not a true VPN solution, as it does not protect you from third-party log attacks (which could leak your information). Unfamiliarity with OpenVPN for many users. Difficult to determine performance and reliability, making them unsuitable for mission critical environments. How do I know if it's suitable for me? There are a few different aspects to consider when determining whether to get an SSL VPN solution or to use an OpenVPN solution. Some of these points depend on the size of your network and the types of devices you might use, but most of them pertain to the types of companies that want to install an SSL VPN, and the types of companies who use OpenVPN: Which VPN service is right for you? Do you just need SSL VPN, or do you want an "easy to use" OpenVPN solution?
