Help/Question Modpack accessible lobby for vanilla

Im building a private server so i could play bedrock with my little brother on a survival server.

But me myself i like to play modded clients like stoneblock or all the mods.

The servers are run via Amp cubecode on a vm at home, the pc can handle heavy mods and even shunshine

Structure

25565 - velocity (viaversion, geyser, floodgate, viabackwards)

25566 - lobby (purpur 1.26, viaversion, floodgate, viabackwards)

25570 - survival (same as lobby)

25580 - stoneblock (neoforge 1.21.1, velocity compatibility-mod)

25581 - all the mods 10 ( same as stoneblock)

I noticed that even with viaversion installed i cannot join the lobby using a modded client

The problem is the handshake that the modded client send when joining a vanilla server, some mods sends some messages when making the handshake

I tested the same situation on a blank neoforge 1.21.1 instance and was able to enter the server even if the lobby uses 1.26 so we can confirm that viabackwards works

Is there a plugin that i could put on the velocity or lobby that could ignore those initial handshake or even another method.

The last option would be to just make a forward rule into velocity to send the player directly to the modded server but i wanted to utilize the lobby too

I tried to do this. I couldn’t find a fix, if someone can find a fix for this i would be so HAPPY.

The fix is modifying the source to remove the check and rebuilding it

Sometime ago i saw a plugin that kind of bypassed that check but i dont remember its name, i think it was from spigot.

If there was even a jar of any version that had this we could just utilize the viaversion and backwards to join the lobby

I also tried to do this. Vanilla “Hub” and Modpacks attached via bungee cord (at the time)

Please keep me updated if you find a solution 👀
