Hi @bastianhoss,  
Unsure if you fixed this or not, but I ran into this issue yesterday so I'll post what I wound up doing for future searches...

```
 if [client_address] =~ /^10\./ {
  mutate { replace => { "[geoip][timezone]" => "Pacific/Auckland" } }
  mutate { replace .....
} else {
  geoip {
    source => "client_address"
    target => "geoip"
    add_tag => ["nginx-geoip"]
  }
}
```
