New GitHub Repo: A Dockerized UDP Broadcast Relay for Multi-VLAN Networks
Why I Built This
If you’ve segmented your home network into VLANs—IoT, Media, Guest, and so on—you’ve probably run into this: UDP broadcast discovery doesn’t traverse VLAN boundaries by default. Devices like an HDHomerun tuner or a Roku sit on one VLAN, and the client trying to discover them (Plex, Emby, whatever) sits on another, and they simply can’t find each other.
Most network controllers (UDM Pro, UniFi Dream Router, etc.) already handle mDNS repeating for things like Chromecast, AirPlay, and HomeKit. But plenty of discovery protocols aren’t mDNS—HDHomerun, Roku’s SSDP, TP-Link Kasa—and those still need something relaying the raw UDP broadcast across interfaces.
