If i try to connect on
51.89.8.4:9987, 51.89.8.6:9987, 51.89.8.3:9987, 51.89.8.7:9987,51.89.8.5:9987
i get redirected to the same server. how can i do this?

Its simple redirection with IPTABLES.

Its simple redirection with IPTABLES.

Not necessary, simple failover IP working good

Or the server has multiple IP addresses.

As everyone else said, the server has access to multiple IPs and it listening on all of them. not hard to do. I used to do it with a minecraft server had it listening on multiple ports, on multiple ips and multiple domains. And all of them could be listed seperatly. had the server listed 50 times, and all my members had to vote on all 50 listings to get a reward, But i made sure it was worth it.

You can do this with teamspeak as well, with iptables

iptables -t nat -A PREROUTING -i eth0 -p udp --dport $srcPortNumber -j REDIRECT --to-port 9987

you could have 10000 ports redirecting to 9987 and you can list them all separately.
