Jun 22, 2007 · Each OpenBSD gateway has a virtual enc(4) interface. This interface receives an unencrypted copy of all traffic sent and received on all IPsec connections. By using pf(4) to filter traffic on this interface we can control the types of traffic permitted on the tunnel. The simplest filter is of course to allow all traffic inbound and outbound.

After much tribulation, I was able to get my FreeBSD machine operating as a gateway router between my lan and ISP router. I used pf because I found a decent howto online - Building an OpenBSD/pf Firewall. The pain came when I tried typing the rules in - what a friggin' nightmare (insert lots of whining and complaining). This article is excellent. Though its based on OpenBSD 3.0, I’ve used it twice to help me set up OpenBSD 3.1 pppoe gateways/firewalls/proxy servers. However, pppoe setup has changed in OpenBSD 3.2 (its gotten much simpler). Hopefully this article will be updated for use with OpenBSD 3.2. Unfortunately there is no portable function for obtaining the default gateway, so every OS needs its own separate function. So to make this work, someone needs to write a get_default_gateway function in route.c for OpenBSD. James Introduction. We'll implement a VPN gateway IPSec/IKEv2 because it's natively supported both by clients (Linux/Windows/macOS) and the server (OpenBSD), no extra software required. Jan 12, 2017 · Hello folks, Here is the output of my uname -a command: FreeBSD biffbsd 11.0-RELEASE-p2 FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24 06:55:27 UTC 2016

# This is in your current subnet.

On the OpenBSD host, all necessary software is already installed. We will configure the system, as well as pf, npppd, and ipsec. First, let’s configure a few system controls: cat </etc/sysctl.conf net.inet.ip.forwarding=1 net.inet.gre.allow=1 net.pipex.enable=1 EOF OpenBSD ships by default with full IPsec support in the stock kernel and provides a set of user-space daemons and tools for managing IPsec configuration, dynamic key exchange and high availability; and the great thing is that, as you'll see, setting up an IPsec VPN on OpenBSD is an incredibly simple and fast task, especially compared to most Jul 07, 2010 · A Note About Default Route (Default Gateway) The default gateway is defined in the file called /etc/mygate. This will allow for your gateway to be set upon boot. This file consists of one line, with just the address of this machine’s gateway address: cat /etc/mygate. Sample outputs: 202.54.1.254 Static Routing With Two Network Interface

I decided to take the opportunity of planned downtime for maintenance to assess OpenBSD as a drop in replacement for Arch Linux as my gateway. I've read (and own) The Book of pf 3rd Edition and Absolute OpenBSD , and had already pre-written a - no doubt very basic - pf.conf based on my exiting Linux configs/requirements. Computer's default gateway (typically the same as that for the network) You will configure your OpenBSD/pf box to be the network's DHCP server. Private IP space: Three blocks of IP addresses which are disallowed on the Internet, but allowed to be used, without registration, Internet Assigned Numbers Authority OpenBSD comes with a secure minimal firewall, webserver, mailserver, and an optional graphical desktop. So if all you want is a few of those things, you do the default install, tweak one config file, and you’re done. Why OpenBSD instead of Linux? It’s uncompromising. It’s not a people-pleaser or vendor-pleaser. OpenBSD use by default ffs2 (Enhanced Fast File System) since version 6.7. If you create a new filesystem manually you will still get an FFS1 filesystem unless you force -O2 or if the filesystem will be larger than 1 TB.
