Networking 2015: Hello pfSense

Having spoken previously about how I’m done with using Cisco for my networks, I now need a replacement. This has come in the form of pfSense. Given that it doesn’t have the name recognition of a brand like Cisco, perhaps some explanation is necessary. The fundamental element of networking is moving packets of information across physical networks. Once upon a time, this required specialist hardware that could move these packets quickly enough, giving companies such as Cisco their market. Today, commodity hardware is cheap and powerful enough that it can act as a network router. This is where software such…

Networking 2015: Saying goodbye to Cisco

For the past five years I’ve been in a relationship that I’ve had no business getting involved with. That is, with Cisco networking equipment. Back in 2010, a friend decided to begin learning Cisco and to obtain his CCNA with a view to becoming a network engineer. Because I can’t resist fiddling with technology, I soon picked up enough to build networks, and eventually had built four of them using Cisco routers and switches. Unfortunately, there’s a  few downsides to using Cisco, which I’ll cover below. In part two of the Networking 2015 series, I’ll introduce the technology I’m replacing…

BT Infinity on Cisco Router: Read This First!

BT Infinity – BT’s implementation of Fibre-To-The-Cabinet (FTTC) is great, especially when you compare it to standard broadband. Sadly the same cannot be said for their provided router (the HomeHub) which is useless, and happens to use your bandwidth to provide a publicly accessible hotspot for any pleb to come along and use. This guide will talk you through setting up a Cisco router to take the place of the HomeHub and teach you how to avoid some of the pitfalls that may otherwise blight your installation. First of all, you need to understand the hardware you have and what…

Well don’t worry because Cisco has done it for you! They provide a range of icons for use in the Microsoft Office suite and some of them should also work in more rubbish office suites.

HowTo: Secure a Cisco Router

With a normal Home / Small Office type router, once you have got it connected, you set a password to log into the web interface and that’s about it for security. But what about with a Cisco Router. This guide covers how to protect a router from unauthorised modification or access to the settings. What it does not cover is securing the connections, which is a topic for another guide. This guide assumes that you are running a fairly current router and IOS and that it supports encryption. On my desk, I have a little Netgear router that I got…

HowTo: Configue a Cisco Router for simple ADSL home networking

So you’ve taken the plunge and gone and bought yourself a Cisco router and now you want to hook it up to the phone line and use it instead of whatever router you currently use. When complete, your router will be able to assign IP addresses via DHCP and route to and from the internet. This tutorial does not cover security or advanced features. This tutorial will go through the basics of setting up an ADSL connection to a non-switching router. It assumes you are capable of basic configuration tasks. The configuration above was tested on a Cisco 2821 1024/256…
