In elasticsearch.yml file of version 5.5.0, I have below:
> http.port: 1180
> transport.tcp.port: `1183`
Then I went through various Elasticsearch documentation ([this](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) and [this](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-transport.html)) and able to expose port 1180 to outside world by configuring below two:
> network.host: 127.0.0.1
> http.host: 0.0.0.0
**Problem** : I am not able to expose port `1183` to outside world (it's only accessible inside localhost). Tried below:
> transport.publish\_port: `1183`
Please guide.

Could you share your logs please?
Use
````
```
CODE
```
````
To format your code instead of

Thanks

**Code** :

# Set the bind address to a specific IP (IPv4 or IPv6):

Please use the right format for code. PREFORMATTED TEXT and not BLOCKQUOTE.
Thanks.
So 0.0.0.0:1180 is the REST layer accessible from another workstation.
But as you defined `network.host: 127.0.0.1`, Transport layer is only available from localhost `127.0.0.1:1183`.
If you want to make both transport and http accessible from outside, do this:
```auto
network.host: 0.0.0.0
http.port: 1180
transport.tcp.port: 1183
```

Configuration `network.host: 0.0.0.0` doesn't work as it throws:
```

```
I have tried setting below to _true and false_, no luck:
`bootstrap.system_call_filter: true`
Can you please help further?

You need to fix the 3 problems you have here:
```auto
[2017-09-29T09:01:19,614][INFO][o.e.b.BootstrapChecks] [node2] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks
ERROR: [3] **bootstrap checks failed**...
```
Sadly you did not share the full logs so I can't help.
But please read [https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html)
That should help.
