On recent versions of pfSense, OpenVPN defaults to subnet topology which uses addresses more efficiently, but if the VPN was configured initially on older versions, or if an older guide was followed, it may still be using net30 topology.

When using a Topology style of subnet, each client will obtain one IP address in a common subnet. When using a Topology style of net30, each connecting client gets a /30 subnet to interconnect itself with the server. See Topology for more details. The following Apr 24, 2020 · OpenVPN is a full-featured SSL VPN (virtual private network). It implements OSI layer 2 or 3 secure network extension using the SSL/TLS protocol. It is an open source software and distributed under the GNU GPL. A VPN allows you to connect securely to an insecure public network such as wifi network at the airport or hotel. A VPN topology defines the way you configure devices to support the VPN. Topologies include remote access, intranet, and extranet VPN. Physical topologies include hub-and-spoke, mesh, and hybrid
OpenVPN in this configuration is essentially point-to-point, and each point gets its own IP address. When you route through the tunnel, you have to specify the near end of the tunnel.
I have found the topology option on openvpn man page but this option seems to be pushed by the server. subnet -- Use a subnet rather than a point-to-point topology by configuring the tun interface with a local IP address and subnet mask, similar to the topology used in --dev tap and ethernet bridging mode. On recent versions of pfSense, OpenVPN defaults to subnet topology which uses addresses more efficiently, but if the VPN was configured initially on older versions, or if an older guide was followed, it may still be using net30 topology. Public IP VPN Topology Dynamically assigned public IP addresses are available in many locations. We recommend public IP connections for day to day web surfing, P2P downloading, gaming, VOIP and other general activities. Whenever you choose an OpenVPN configuration labeled “Public” you are randomly assigned your own public IP address.
OpenVPN Cloud allows the configuration of strict access controls. Controls can be put in place that will restrict access from Networks, Hosts, and User Groups to fine-grained services defined under Networks and Hosts. The sections below illustrate some of the ways access controls can be used.
Jun 04, 2014 · This page discusses the concepts of addressing in OpenVPN. Addressing Basics for Server/Client. Addressing in OpenVPN depends on the Topology in use. The 3 types of possible server/client addressing styles are explained in the Topology page and are: subnet The preferred topology for server/client steups net30 OpenVPN Cloud allows the configuration of strict access controls. Controls can be put in place that will restrict access from Networks, Hosts, and User Groups to fine-grained services defined under Networks and Hosts. The sections below illustrate some of the ways access controls can be used. INTRODUCTION. OpenVPN is an open source VPN daemon by James Yonan. Because OpenVPN tries to be a universal VPN tool offering a great deal of flexibility, there are a lot of options on this manual page. We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will remain NSIS-only. Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless So. Installed 10.0p7 and openvpn git master today, tested with topology subnet, announcing a /24 from the server. This is what I have: fbsd100.ov$ ifconfig tun0 tun0: flags=8051
