ZeroTier is a "network hypervisor." It creates a virtual network. So how is that different from OpenVPN? The name literally means a private virtual network.And with tun/tap devices it can do it on different layers of the network stack.
TAP is bridging whereas TUN is routing. From the OpenVPN Wiki: TAP benefits: behaves like a real network adapter (except it is a virtual network adapter) can transport any network protocols (IPv4, IPv6, Netalk, IPX, etc, etc) Works in layer 2, meaning Ethernet frames are passed over the VPN tunnel; Can be used in bridges; TAP drawbacks: Feb 11, 2016 · This post is a continuation of that post. So we already have a bridge configured (br0) running openvpn in TAP mode. Now we want to add a second listener in TUN mode for iOS. We will reuse the same key (hence we use duplicate-cn option in both server configs) The OpenVPN side is easy. OpenVPN will scan for .conf files in /etc/openvpn so just: OpenVPN Protocol (OpenVPN) With OpenVPN, you can tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port. $ 0 00 /Monthly. TAP-Windows driver (NDIS 6) This is an NDIS 6. I better pay Openvpn Tap Vs Tun Ios a few bucks every month for a trustful provider than think about "free VPNs" and how they are selling my information. OpenVPN configuration package download To install the VPN client, here you can find the proper configuration files base on your client operating system. For Windows and MAC, the configuration is using TAP mode for best compatibility for applications. For iPhone and Android, the configuration is using TUN mode due to OpenVPN APP limitation. TAP, namely network TAP (Terminal Access Point), simulates a link layer device and operates in layer 2 carrying Ethernet frames. TUN is used with routing . TAP is used for creating a network bridge . I always set up tun. Tap is used by ethernet bridging in OpenVPN and introduces an unprecendented level of complexity that is simply not worth bothering with. Usually when a VPN needs to be installed, its needed now, and complex deployments don't come fast. The OpenVPN FAQ and the Ethernet Bridging HOWTO are excellent resources on this topic.
This page describes how to create a network bridge on Arch Linux and host an OpenVPN server using a IP layer-2 based Ethernet bridge (TAP) rather than a IP layer-3 based IP tunnel (TUN). The general OpenVPN page describes setting up PAM authentication or OpenSSL security certificates in more detail.

You can run as many copies if you will of openvpn that you need, different auth settings, different certs, different ports - or lots of stuff the same just a different port or protocol (tcp/udp).. You could have one that is tap, and others that tun, etc. etc.. 468 * an OpenVPN client tries to connect from a public location that is also running. 469 615 msg(M_FATAL, "Error: problem with tun vs. tap setting");
