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).

Configuring the IPsec gateway. 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
In the following, I assume you have chosen your server provider, and have a running OpenBSD 5.6 freshly installed. If you want installation instructions, you can check my OpenBSD VPN gateway article, keeping in mind it's best to let your interface in DHCP while installing it for the first time on your VPS. I also assume you have one root and To print traffic neither sourced from nor destined for local network 192.168.7.0/24 (if you gateway to one other net, this stuff should never make it onto your local network): # tcpdump ip and not net 192.168.7.0/24
OpenBSD Firewall / VPN using IPsec (site-to-site) This document will guide you through a very simple site-to-site VPN setup. A lot of the same information can be found in the vpn(8) manual. A few assumptions will be made here: * You are using OpenBSD as the Firewall / Gateway / VPN endpoint at each site.
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.
