UDP over internet

[mrn]

hi,
i would like to create a udp stream through the internet.
actually, i can create stream available from my local network, and all work fine. but, i can't access to this stream from the internet.
i've already done my port forwarding in my router. i've also tried to create stream with my public ip as setting but i can't connect.
i've understood that i can't use udp multicast through internet (it seems logical) but udp unicast should work ?
thanks

Creating a unicast stream with public IP is the same as creating a unicast stream inside the LAN.

hi, thank you for your fast reply.
in the stream configuration, for ip parameter, i've set my public ip, i've opened the ports on my router. but i can't connect from an other device on an other network.
i 've also tried to set the public ip of the receiver but i can't connet to the stream.
i'v seen on the internet that people put an "@" befor the ip for th receiver (ex : "udp://@xxx.xxx.xxx.xxx:9638")
what is the use ? is it for tell to vlc to search on the local network ?

thanks

ps : i've disabled my firewall for that
