Note: To proxy to my host that’s running traefik and docker, I need […]

It seems most media servers (Jellyfin, Emby, Plex, UMS…etc) recommend using docker host networking (-net=host) when running within a container so that it can see UDP traffic on port 1900 for DLNA discovery. This is undesirable for a number of reasons, not the least of which is that a reverse proxy (Traefik, perhaps?) running in […]

Netgear Web Managed Smart Switch Configuration
Netgear Web Managed Smart Switch Configuration

This post explains how to configure the line of Netgear Web Managed Smart Switches WITHOUT installing their configuration utility (using only your web browser).
