In this guide we're going to take a look at how we can use cheap and "low end" hardware to build an amazing OpenBSD router with firewalling capabilities, segmented local area networks, DNS with domain blocking, DHCP and more.

We will use a setup in which the router segments the local area network (LAN) into three separate networks, one for the grown-ups in the house, one for the children, and one for public facing servers (a DMZ), such as a private web server or mail server. We will also look at how we can use DNS to block out ads, porn, and other websites on the Internet. The OpenBSD router can also be used on small to mid-size offices.

Recent and not so recent changes in OpenBSD that make life better (and may turn up elsewhere too).

Known to be "functional, free and secure by default", the OpenBSD operating system has played an important role in open source for more than a quarter century. It has also been fairly central to what I have done for the last two decades and some. What follows is my personal view of what life with OpenBSD has been like, with an emphasis on moments and developments that I feel made life, or at least my life, better.

Dynamic DNS Daemon for OpenBSD.

dyndnsd is a Dynamic-DNS daemon for OpenBSD. It is minimal, lightweight, intuitive, and generic/extensible enough to support any Dynamic-DNS provider.

Fair Internet bandwidth management on a network using OpenBSD.

The point of this article is to explain how to use OpenBSD as a router on your network to allow the Internet access to be used fairly by devices on the network to guarantee everyone they will have at least a bit of Internet to continue working flawlessly.

I will use the queuing features from the OpenBSD firewall PF (Packet Filter) which relies on the CoDel network scheduler algorithm, which seems to bring all the features we need to do what we want.

Support OpenBSD’s pledge(2), unveil(2) in programming languages.

Some years ago OpenBSD 5.9 bring support of pledge(2) and later OpenBSD 6.4 bring support of unveil(2) system calls. Initially only C/C++ applications had possibility to use these system calls. Later people from community added support to many other programming languages that allows to use pledge(2) and uneil(2) in the most popular languages. Table below helps to understand status of it’s support in these languages...

I got the J language working on OpenBSD.

J is an array programming language. That is to say, the fundamental data type in J is the array. J is a successor language of APL.
