idRO Classic, Poseidon cant work after Gameguard update

[jetstrike5566-bot]

Describe the solution you'd like

Openkore version : openkore-master from github

Server: idRO Classic

Feature Request: Poseidon server shows "no msg" window and dc , openkore dc after that.**

I have a little bit experience at Visual Basic when i was in high school.
Last Saturday i want to build a warp bot for GVG so i started try to set parameter in openkore.
I googled and found some informations at Openkore Official Forums (how to set a poseidon server for idRO classic server , poseidon.txt ,config.txt,
client.xml in data.grf ), openkore finally works.

But, after Gameguard update from last maintenance(8/21), the poseidon server doesnt work anymore.
I googled and find #3964 have a same problem in May, and looks like they solve it.
But the solution is in Openkore Official Forums and it's already dead now. dead solution

After that i try to change the ip and port of poseidon in data.grf ,and it doesnt works.
This seems to be relate to packets , and it's obviously beyond my knowledge

Can someone teach me or help me? So i can do it by myself when i meet the same situation again.

@alisonrag master of openkore please help me..

Today I tried by my self and I can confirm that you can bypass this protection if you run Poseidon and Openkore on another machine. My advice is to run Openkore and Poseidon on a VM and the Ragnarok client on your physical machine.
In my tests I was using the current Ragexe and the same server type you are using, but in the current Ragexe the "/account" parameter does not seems to work, so I did a manual redirect of the client network traffic througth my router.
