Blocking IP Cameras from Talking to the Internet
The recent distributed denial of service attack is said to have been caused by the Mirai botnet which basically turns IoT devices in attackers. One of the devices that is vulnerable is an IP camera that has a default username and password. While I don't have that brand of camera, my cameras have accounts that I can't remove and apparently one ONVIF account with a username/password that can't be changed. I'm pretty good at securing my network from people coming in, but what about things going out? A lot of these IoT devices talk to a server for firmware updates or whatever. Since my IP cameras only need to talk to my server that is recording video, there is absolutely no need for them to connect to the Internet. I decided to see what I could do to isolate the traffic; this is something I've wanted to do for 3.5 years ever since I got a Cisco router that did VLANs, but couldn't figure out a reason and didn't have the knowledge to do it. However, times have changed.

Review: Ubiquiti UniFi Security Gateway
Sometime after I reviewed the Ubiquiti EdgeRouter Lite, Ubiquiti contacted me and offered me a few products to test and review. One of the products they sent me was the UniFi Security Gateway. At the time, I set the box aside as it didn't have all the features of the EdgeRouter Lite. In January when my father was having trouble with his Internet, I put the USG into service. For that application, it was ideal as it integrated with the rest of the components and was simple to manage.

Printing on a Glass Bed and printing really flexible filament
When I purchased the Ender 3 Pro, I liked the idea of the magnetic flexible bed so that prints would easily come off of it. Reading on various forums, a large number of people seemed to prefer glass beds with either hairspray or a glue stick to get prints to stick to the bed. I've had good success with the magnetic bed, so I just filed the glass bed information in the back of my head.

Setting up WAN Failover on a USG
For many years, I've been intrigued about routers that have cellular backup to maintain connectivity when the primary Internet does down. I've never pursued setting this up as my Internet connection has been quite reliable with downtime measured in hours over the last few years. The cost to set this up could never be justified for my home setup.
