can n2n support UDP multicast

thanks for your great work! I want to know n2n 3.0 is support udp multicast

If I remember correctly, n2n is able to handle multicast packets. But they are dropped by default. -E at the edges lets them accept these packets. n2n network-wide, multicast is treated like broadcast so they are forwarded to every edge which then needs to filter itself.

I use udp multicast in java，and start edge service with E；but still not receive udp package

I’m sorry for the inconvenience. If I start with the “-E” parameter on the edge node, what should I fill in for the multicast address when I send a multicast?

Any multicast address (to which your application is interested in) should work. The multicast on virtual network adapter should work just as a with a regular network adapter.
