Is it possible to route broadcasts across subnets/networks with openwrt? What software do I need for it?
For testing I've just splitted 192.168.1.0 into /2x25 subnets. I'm able to ping and have direct access (ssh, etc. working) between the clients. But some software e. g. Minidlna or Syncthing is relying on broadcasts ... and ofc they are sending out only to 127 respectively to 255 dependig on subnet the client(s) belong.
E. g. for Syncthing I've read that they send out broadcasts on ipv4 only and multicasts for ipv6 only. There is not "button" or sth. else to change that behaviour for ipv4 and I don't have ipv6.
With direct IP I've already tried for syncthing. It's not working.
For Minidlna it is working. SSH and SAMBA is working too.
I think the only option I could try is to setup up a local relay server for syncthing. the global server I don't want to use.
