Multicast between subnets

NethServer Version: 7.6
Module: firewall


is it possible to configere the NS firewall so that multicast messages from one interface (green) are forwarded to another interface (blue, red)? I would like to relay udp packets from multicast address, port 1900 into another subnet. I guess this must be something else than just an ‘allow’ rule in the NS firewall web interface?

Any idea?



yes SSDP - to find the Sonos Controller.

I need to move the Sonos boxes into another segment which is always online. Sonos does not remember the last play list / radio station when there is a disconnect from the LAN.

This means uPNP…
