  • Wireguard on Unifi

    In a recent Beta firmware for various Unifi cloud consoles, Teleport was released. Under the covers, this appears to be run over wireguard. I have been using Wireguard as VPN for some time, though when I migrated off my USG I have had to run this from a raspberry pi in my network instead. After […]

  • Valid SSL certificate on a UDR

    I recently got a Unifi Dream Router as an upgrade from the Unifi Security Gateway. One of the differences is that the controller is hosted on the router itself, i quite often use the local access as opposed to going via Since this is exposed locally on 443, i wanted to be able to […]

  • Debugging SQS::QueuePolicy in AWS

    At work I needed to deploy an SQS queue along with policies to restrict access to the correct roles. I came across an annoying error, which took way to long to figure out.

  • Client auto connect with openvpn
