Most Minecraft proxies drop the early login packets AutoModpack uses, so a standard proxy setup breaks the modpack connection. The proxy has to forward those packets.
| Proxy | Status | Setup |
|---|---|---|
| Velocity | Works | Needs a patch plugin and MAGIC |
| Gate Lite | Works | Port configuration |
| Gate | Fails | |
| Waterfall | Fails | |
| BungeeCord | Fails |
Velocity
Velocity does not forward the packets on its own. Install the official AutoModpack Velocity plugin and set connection-mode to MAGIC.
Gate Lite
Gate Lite forwards the packets out of the box. What needs care is routing: the client dials the advertised endpoint, controlled by advertised-endpoint-host and advertised-endpoint-port, and that route has to reach the backend in a shape the selected connection mode accepts. It does not have to match the backend's bind-address or bind-port.
