charon.plugins.forecast.interface = Local interface to listen for broadcasts to forward. Name of the local interface to listen for broadcasts messages to forward. If no interface is configured, the first usable interface is used, which is usually just fine for single-homed hosts. If your host has multiple interfaces, set this option to the local LAN interface you want to forward broadcasts from/to. charon.plugins.forecast.reinject = CHILD_SA configurations names to perform multi/broadcast reinjection. Comma separated list of CHILD_SA configuration names for which to perform multi/broadcast reinjection. For clients connecting over such a configuration, any multi/broadcast received over the tunnel gets reinjected to all active tunnels. This makes the broadcasts visible to other peers, and for examples allows clients to see others shares. If disabled, multi/broadcast messages received over a tunnel are injected to the local network only, but not to other IPsec clients. charon.plugins.forecast.groups = 224.0.0.1,224.0.0.22,224.0.0.251,224.0.0.252,239.255.255.250 Multicast groups to join locally, allowing forwarding of them. Comma separated list of multicast groups to join locally. The local host receives and forwards packets in the local LAN for joined multicast groups only. Packets matching the list of multicast groups get forwarded to connected clients. The default group includes host multicasts, IGMP, mDNS, LLMNR and SSDP/WS-Discovery, and is usually a good choice for Windows clients.
