convey multicast (to another LAN) through WAN disabling multicast

My Server and Client run both on Linux.
The Server broadcasts multicast, the Client listens multicast.

My Client has to migrate to another site,
and unfortunately multicast is not allowed between the two sites :-(

How to convey multicast between the two sites?
- Through TCP or UDP?
- What tools do you recommend?
- What about latency?

I received an good answer about Cisco configuration (GRE),
but one of the network teams do not want to monitor/maintain it,
therefore transmission may break several times per year
and support team will spend too many hours to understand and repair the incident.

Please, feel free to propose any alternative...
for instance based on Linux kernel features for low latency purpose
An usage example will be appreciate :-)


Current: Server and Client on the same site

,--------.    ,----------.
| Server |    |  Client  |
| sends  |    | listens  |
|multicst|    | multicast|
|  IP1   |    |   IP2    |

    |______________|
     LAN |

                 WAN              

Future: Server and Client, each one on a different site

,--------.   ,-------.    ,----------.
| Server |   |       |    |new host  |
|        |   |       |    |for Client|

       | LAN of site1            |LAN of site2
       |_________________________|
                    WAN

multicast channel: 224.1.0.1:6666
