You can use ip multicast helper-address 239.2.2.8 172.16.2.0 ACL,
Ip forward-address udp xxxx
Access-list permit udp any any eq xxxx
Where is xxxx is the udp port which you will map for no multicast
clients for example 2000

That's good to know, but it still wouldn't work. The client applications
do
not have multicast ability.
Best,
