Just works and has more feature than OnlyProxyJoin. It is a must for every server owner that don't want their servers griefed.

Been using this for years, would recommend.
I have a config that I can paste in any server of mine to set it up.
Bought the source of him for €10. I'm making a fork, might put it on spigot, might not.

top 1 BungeeCord plugin fixing all port exploit attacks and saving ip forward never miss targets 5 STARS <3

Hey, wie ist das mit Dynamic IP?
Funktioniert das auch in irgeneinerweise?
--------------------------------------------------------------------------

A great plugin and works as said. I had a bit of problems (my fault) and the author was happy to help me. Great plugin and author.

ist es bereits kompatible zur 1.17 ? wollte bei zeiten updaten und würde nur ungerne auf das plugin verzichten tut was es soll und das seit über 1 jahr Nice:)

I really like this plugin, I would like you to advise me, I have a little problem with it

habe jetzt diverse anti proxy plugin getestet, dieses ist das einzige, das funktioniert.

Betreibe seit einem Jahr meinen Survival Server und seitz 6 Monaten auch mit dabei das "PreventPortBypass" Plugin.

Zusätzlich zu "IPWhitelist" leistet das Plugin gute Dienste!

Wer schauen möchte:
Server: legends-craft.net (1.16.5)
#Survival und AcidIsland auf SCHWER#

Vielen Dank und Grüße

Dosen't work for me, always getting the kick message, while everything is configured well

Perfect plug-in. Does what it says. I only needed to set up the plug-in to work for the IP address "172.18.0.1" and everything works exactly how it's supposed to.

Does what it says. Works nicely with my plugins that are a bit special. 5/5 stars

Es ist ein super plugin!
Wäre schön wenn du ein Feature hinzufügen könntest, dass custom commands ausgeführt werden.

This is a really good plugin! It stopped hackers from exploiting my server.

It would be very nice if you added a feature that runs a command when someone doesn't join to the proxy.

works as described! Thanks for the resource, very well designed one suggestion is to allow ports as the root IP

An excellent plugin, I use on my servers, also want to note this plugin works quietly on Paper 1.16.1 and 1.16.2 - I have been using several days, there no errors from it on these versions.

Respect author

My Server: mc.draimcido.ru
Discord: discord.com/TBeK3nE

As I said earlier, I'll give it a try, it works for me on 1.16.1 spigot version.

Very nice. It's protecting my server and avoid hackers login another account. Really recommend this

FYI this does not work on Pebblehost hosting, thus i am no longer recommending them. im sure this works great but pebblehost doesnt let you configure all parts of the bungeecord config (resets the host ip to 0.0.0.0 everytime)

EXTREM gut hab vieles probiert mit freunden keiner ist durchgekommen extrem gut ich hoffe falls neue bypasses kommen fixt du sie auch ;D

Developer was very nice, and plugin seems good as well. However, I was unable to use it due to my host having some restrictions which is unfortunate. I'd recommend this plugin to whoever is able to use it.

Wow I love this, it's so easy! To be clear we would set the bungee origin ip to the computer's ipv4 address if the bungee server and spigot servers are all hosted on the same machine, correct?

Excelente recurso, los ipwhilist son una basura.
Su trabajo lo hace muy bien preciso y facil.

Make immunity for a player's nick (without UUID) to enter the server without checking. (dedicated server, stay at home and I can't connect to the server). The plugin works great!

Thanks!

This plugin works flawlessly and prevents a major bungee exploit! Thank you such

A most excellent plugin to prevent the port by pass, which nefarious users (usually kids who saw a youtube video) can use to obtain OPS.

I very like to use this plugin but thought was dead, now its come back again :-D

Unnormal gutes Plugin feier ich gute Arbeit einfach einzustellen.

Wenn du magst mein Server nutzt diese Plugin nun auch IP: SplashBlock.net MFG :)

Gutes Plugin.
Mir Wurde direkt im Teamspeak weitergeholfen
Funktoniert Einbahnfrei!
Kann ich nur weiter empfehlen
Sehr Gute Arbeit!

--------------------------------------------------------------
not work
--------------------------------------------------------------

No support for multiple BungeeCord instances (load balancing) connecting from different IPs to a Paper/Spigot server with this plugin.

works well! super easy to set up! tested both cases of correct and incorrect addresses and it actually does work!

Great plugin. Stopped griefers from using the proxy bypass exploit. Sent a donation to encourage further development.

works perfect no lag and protect my network, plugin helped me to protect my network

Super Plugin nur eine Frage:
Muss man das Plugin in die verschiedenen spigot Ordner (Unterserver) packen oder in den BungeeCord Order (Haupt-Server)

I need help with this error: 20.08 11:26:33 [Server] WARNING Error enabling plugin PreventPortBypass

Hey, ich benutze PPB auf meinem Netzwerk, allerdings kann ich es auf einem meiner Server (1.7.10 Thermos) nicht nutzen, beim joinen steht dann immer, dass ich über den Proxy joinen soll.

Kann sein, dass ich was falsch mache, aber die config is 1:1 wie bei der Lobby und dort geht es.

Works if you are hosting from a single dedicated IP. I however use multicraft host(S), so if you are trying to setup a bungee with multiple IP's this will not work.

Como eu posso usar esse plugin em minha VPS todos os ips sáo iguais

ES: How can I use this plugin in my VPS all ips are the same

Hey wir Benutzen dein Plugin und es Funkt. einwandfrei! Super Plugin danke dir LG

IP: SplashBlock.net

Ein sehr gutes Plugin, um sich vor Hackern zu schützen, die sich über BungeeCord OP geben.

Cooles Plugin!
Besteht die möglichkeit mehrere IP-Adressen als wie nur eine?
-------------

Richtig gutes Plugin. Einfach einzustellen, man alles ändern wie man will. Was will man mehr? :D Danke für das Plugin! :)

The Best Plugin For Prevent Hack Attack.
Quick install, and works super !!!
