Guide L2Proxy - A simple Proxy for Lineage 2

[YulRun]

Anyone been able to get L2Proxy working with AAC?

With AAC off, L2Proxy works 100%. With AAC on, can't get past the Server Select.

There is nothing special to adat. The service itself is cross-chronicle and the l2j code is so minimal it should be easily adaptable

Is it possible to give a tip on how to install this in any Cloud service such as AWS GCP or Azure.  No matter how i tweak the firewall settings inside every VPC i get the same error

 

Unhandled exception. System.Net.Sockets.SocketException (99): Cannot assign requested address at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, String callerName) at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Bind(EndPoint localEP) at System.Net.Sockets.TcpListener.Start(Int32 backlog) at L2Proxy.Proxy.L2Proxy.StartAsync(CancellationToken cancellationToken) at Microsoft.Extensions.Hosting.Internal.Host.StartAsync(CancellationToken cancellationToken) at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token) at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token) at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.Run(IHost host) at L2Proxy.Program.Main(String[] args)

 

Seems that the ports not listening. In general seeems that their network is different from other services. Each port is opened and listening to icmp. Thank you . 

 

 

Solved. If someone wants to use those cloud services as proxy machines in the appsettings.json file just use the private ip adress cloud service gives you. In the proxy.xml file inside server files (main server) use the external ip adress.

What if we have gameserver separate from login server ? (2 different machines communicating with each other). I tried to replicate that and i made 3 different machines. One in Ovh 2 in google cloud.  I was able to connect trough the main server id 1 but not with the proxy one which it seems healthy regarding the status.  This is my console log in the connection 

info: L2Proxy.Proxy.L2Proxy[0] Established playerip:52177 => server ip which is managed from the login server so its not the original gameserver ip:7777

info: L2Proxy.Proxy.L2Proxy[0] Closed playerip:52177 => server ip:7777

 

Thanks and sorry for the double post. I am just trying to figure out some ways of hiding the real ip both trough ini and from the netstat of every computer. I know its not 100% protection but its something. 

 

Thanks.

Thanks for sharing your L2Proxy tool - it sounds like it could be useful for people looking to set up a MITM proxy for their L2 server. Could you elaborate a bit more on how the L2Proxy service works? Is it a stand-alone application that players can connect to, or does it need to be run on the same server as the L2 game server? Also, I'm curious about the extra functionality that the L2Proxy service offers - could you give some examples of what that might be? I always used only the proxies from https://soax.com/mini-proxy-online, and I want to try something different. Answering these questions will help me a lot. Thank you.

Why do all players only have one IP address, which is the proxy's?

I did several tests and created a debug to collect all IP addresses that connect to the proxy. It collects them correctly, but when they are sent to the server, they get lost and stay with the proxy's IP address.

• RealIP - Usually with MITM proxies, since the traffic is funnelled from one server, you normally lose the real IP of the player which limits a lot of the functionality that you might have implemented. L2Proxy allows the LoginServer to pass the real IP of the used to the Gameserver during the Login->Gameserver player handoff
