How would I change/make sure that my windows host receiver of multicasted udp datagrams is set to be able to receive an MTU of 1500?
The documentation I’ve read so far refers to PPP and PPPoE, which doesn’t seem to apply to udp datagrams.
Thanks

PPP/PPPoE are not mutually exclusive with UDP. The former are link layer protocols, the later is a transport layer protocol, see TCP/IP.
If you are talking about ethernet – you already have it. 1500 is the default ethernet MTU.

Then you usually don’t work against ethernet directly. It’s UDP (multicast), so subtract (at least) 20 bytes of IPv4 header, and 8 bytes of UDP header. That gives you maximum of 1472 bytes for multicast data payload.
