To answer your question yes it does support UDP. But to add no it does not support the multicast ip address.
The images shows the inbound and outbound rules broken down by protocol and ip ranges for the AWS image. The outbound has no limits all protocols and all IP's but the inbound shows all protocols but limits the ip thus does not include the address 231.7.7.7 but will allow UDP. No need to respond and thanks for you help I'll figure it out.
