HTTP unicast to MULTICAT address

[yboujraf]

Hi,
I am using VLC for redirect to a multicast address a SAT receiver who is streaming in unicast http.
I am not expert in NETWORK but my question is :

How can I configure my network card of my server for using a Multicast address ?
Other question is :
Is it possible to the same Network card, to have a Multicast and unicast address?

Best Regards,
Youssef
