For a client who operates a campsite, I installed a new Aruba 7010 WLC with a few outdoor AP’s (AP375’s). The campsite runs a PfSense firewall that also serves a captive portal page for guest WiFi access. Getting the Aruba WLC to play nice with the external captive portal was not very straightforward. In this post, I explain the challenges I ran into and how to solve them.
The old wireless network runs on a Ruckus ZoneDirector WLC.

On Cisco switches that do not perform routing, setting up a default route or a default gateway can be a little bit confusing. I’ve seen some configuration drift in our network recently were incorrect settings caused some switches to become unreachable for management. Read on to find out the details.
After some switches went offline for management, I discovered they had both the ip default-gateway and the ip routing setting enabled.

While preparing to dive into Ansible and Nornir a lot more, I decided to set up a good lab environment. Making use of Eve-NG and some well-known Linux tools, you can build whatever you need. I’ve built a simple topology based on Cisco for switching and Juniper for routing, to try out any automation tool I choose. Read on to find out more.
For practicing different network automation skills, I’ve had the idea for a while already to build some kind of multi-vendor lab network, then connect that lab to a management server.

I had to migrate my reverse proxy away from the PfSense package to a standalone solution. One requirement was having automated certificates from Let’s Encrypt. Manually setting up all kinds of Linux applications will become tedious, so once again we’re looking at leveraging Docker to simplify operations.
The PfSense package for HAProxy has kept me reasonably happy until it didn’t. The package is brilliant for quickly getting a reverse proxy running including SSL offloading with Let’s Encrypt integration.
