# Firewall Problems

## Native Clients

Downloading and running the MSquared client requires access to [GCP](https://cloud.google.com/). Some corporate firewalls block access to certain ports or IPs used by GCP, which can prevent this working. You will need to allow the following ports and IPs:

## GeForce Now

### Ports

In order to access events & content via Nvidia's GeForce Now pixel streaming, you should open the following ports:

> * 49003 – UDP Inbound AUDIO
> * 49004 – UDP Outbound AUDIO
> * 49005 – UDP Inbound VIDEO
> * 49006 – TCP/UDP Outbound/Inbound Remote Input
>
> If GeForce NOW is running behind a corporate or school firewall, the firewall should allow traffic to/from GeForce NOW servers’ UDP ports between 10000 and 20000.

(See [this Nvidia support page](https://nvidia.custhelp.com/app/answers/detail/a_id/4504/~/how-can-i-reduce-lag-or-improve-streaming-quality-when-using-geforce-now%3F) for more context.)

### Testing

You can check whether your network is blocking pixel-streaming traffic by trying to access an event or content and seeing whether you are presented with an error similar to:

<figure><img src="https://1456550285-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FoWTlPaoHd1McSakqMigu%2Fuploads%2Fgit-blob-b2e7ad847d3f1a7759381863cea44322b982999e%2Fimage.png?alt=media" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
If you are reading this page in preparation for a platform evaluation - you can see if pixel streaming is blocked on your network by going to <https://construct.msquared.io/> > `Construct Main` > `Play Now` > `Join on web` > `GeForce Now` and seeing whether you experience the error above
{% endhint %}
