I recently bought the Amcrest video doorbell (affiliate link) since I like my other Amcrest IP cameras, and I wanted a doorbell that was less cloud connected (the Amcrest doorbell requires an online account for the initial configuration but can be used completely offline at the expense of losing push notifications to answer the doorbell). The doorbell has the RTSP capability, so the video stream can be recorded based on motion events and/or 24/7 recording with video surveillance software like BlueIris or hardware such as the Amcrest NVRs (affiliate link).
In my network, I created an alias for all of the ports I have open on my server so that I can create firewall rules to allow several of my VLANs to access the services hosted on my server. The benefit of creating an alias is that I do not need to create 4 separate firewall rules to open 4 different ports to my server and then repeat this process for each VLAN I need to allow access (yes, you could use floating rules or rule groups depending on the order you need rules to be processed).
A few months ago, I switched to using my own cable modem instead of using the ISP provided modem/router, and I wanted to access the web interface for the cable modem status. Another reason was to change the default password if it had one since default passwords are not secure. The default web address for cable modems is typically http://192.168.100.1. Perhaps that is a common default IP address to avoid potential IP address conflicts with standard consumer grade routers which often default to 192.
When setting up Cloudflare for this website, I decided to try it out on some sites that I had setup on my home network. In particular, my Nextcloud web portal. All was going well until I began enabling various optimization features that are available in the free Cloudflare account. I noticed when accessing the Nextcloud web page from my work computer that it would not allow me to log in. The login button was visible but disabled.
After the long journey of learning more about IPv6 and how to enable it on my home network (see my page for detailed info), I discovered that I broke some functionality. When you have IPv6 enabled alongside IPv4 in a dual stack configuration, IPv6 will often take priority – after all, it is newest protocol intended to replace IPv4. I have created a network for my IP security cameras that is isolated from the Internet that I use as baby camera monitors.
