# Blocking Forge mods

## How to block FORGE mods

{% hint style="warning" %}

### Limitations (ViaVersion + Bungeecord)

Precise mods list may not be available on Bungeecord networks.\
It may be a Bungeecord limitation or bug, I'm currently investigating.

* 1.8 to 1.12.2 server <mark style="color:red;">won't</mark> detect mods of 1.13 to 1.16 client
* 1.13 to 1.16 server <mark style="color:green;">will</mark> detect mods of 1.13 to 1.16 client
* 1.8 to 1.16 server <mark style="color:green;">will</mark> detect mods of 1.8 to 1.12.2 client
  {% endhint %}

You can easily block them just opening the file `clients-config.yml` and adding them to the list like that:

```yaml
  block-clients:
    forge:
      enabled-check: true
      description: "Forge"
      brands:
        enabled-check: true
        list:
          forge: true
          fml: true
      channels:
        enabled-check: true
        list:
          FORGE: true
          l:forge: true
          FML: true
          l:fml: true
          "FML|HS": true
          "fml:hs": true
          "fml:loginwrapper": true
          "fml:handshake": true
          "fml:play": true
      forge-mods:     
        enabled-check: true
        list: #             <-------------------- HERE
          5zig: true
          forgewurst: true
          schematica: true
          worlddownloader: true
          # ....
```
