Tutorial: Using VMWare ESXi and PFsense as a network firewall/router
August 31, 2015
vSphere In most networks, you will have dedicated hardware to function as your “edge” (firewall/router). This is typically for the best, but there are always cases where you can’t put out that dedicated hardware. Sometimes it’s for cost reasons and sometimes it’s for complexity. In my particular case, I was installing an ESXi server in a datacenter and only had 2 amps of power to work with, of which my server took up ~1.8amps at peak load. So cost came into play and we simply couldn’t afford to put in dedicated hardware that could push enough bits. In such cases, it is possible the setup ESXi on the network edge, in a reasonably secure fashion, with PFSense acting as a firewall.
Project “Falcon” – The DIY Router (server?) Experiment
April 14, 2015
As previously mentioned, I work in a “Cloud company” which typically means we claim we’re a “serverless” office. However sometimes I need a server-like machine to make a point. For this particular project we needed a machine that was, for all intents and purposes, a server… except I wanted to build it myself. It wasn’t so much to save money, but so I could customize the machine to get exactly what I wanted out of it (and because it was a fun diversion). The result of that was known as “Project Falcon”.
Erase the configuration on Cisco 2600/3600 Routers
August 5, 2010
A bit back I decided that I should investigate following the Cisco Certification path. The lower levels aren’t hard, but all things considered, you really need to have a “test lab” of equipment to play with. So a few weeks ago I was offered a pair of old Cisco 2600 series routers on the cheap, and decided to pick them up. Around that time I also acquired myself a number other old Cisco devices including some PIX, switches, and a 3600 series router. The problem is, they all had passwords and I didn’t know any of them. Turns out it is super easy to reset routers in the 2600, 2800, 3600, and 3800 series back to the factory default.
