    Hello guys,

    I have questions about udp proxy redirect and i want ask for isp or network master r4p3 member.
    You know some firewall, ddos mitigation services using udp proxy redirect method.

    This method's logic is one ddos protected server (for example: hosteam.pl servers) udp port redirect to another non-protected vps server.
    For example working logic:
    178.217.0.0 port: 1111 -> (redirect to) 185.26.140.0 port: 9987
    So you connect 178.217.0.0:1111 you will auto redirect to 185.26.140.0:9987
    So if we do this then user will cant know our non-protected server ip and we have protected our non-protect server.

    And my question is how can we do this?

    Already thanks for all comments.
    (Sorry for bad english)

    Install a GRE tunnel. Then you can use the protected ip to connect to your server.

    Gre tunneling logic is all traffic coming before protected server and outgoing to non-protect server.
    I dont want this shit, i mean only redirect with udp protocol.
    So like cloudflare SRV records. (only for safely redirect)
    Thanks for your idea.
    Anybody have another solutions?

    Simply setup a gre tunnel. Anything else will not work and its easy to get your real ip. Because teamspeak need the real server ip to communicate ;)
