You normally cannot multicast over the Internet, unless you have an ISP that specifically provides for this.

If you are just trying to cross a connection between two locations, connected with routers, you need to increase the time to live value. The VLC default is 0, so that the packets do not get pushed beyond the local segment. Look under settings -- preferences (check the Advanced options checkbox). There is a TTL value down in sout-access -- access_output_UDP. Make it, say, 4. There is another TTL value somewhere, general network control, try also increasing that to 4.

You also, of course, will need a router that supports multicast.

One caution -- be careful in using multicast, so you do not flood people. If you wish to use this in a corporate or college environment, check with your IT staff first.
