# How to protect your Rust server

***

### Opening game-port(s)

There are a few ports (by default) that we will need to whitelist to allow users to connect to your server through our firewall.

Head to the **Firewall Rules** page, and open **UDP Port 28015** this is the default rust game-port and will allow regular game traffic through to your server.

### BattleMetrics (Optional)

You may need to whitelist RCON solely for BattleMetric IP's as listed below

BattleMetric IP's as of 04/2021

&#x20;   51.79.45.167

&#x20;   142.44.175.123

&#x20;   167.114.219.233

&#x20;   51.222.127.205

&#x20;   51.222.127.206&#x20;

&#x20;   51.222.127.207&#x20;

&#x20;

You can do this by creating a rule similar to the image below (allow rule with strict source ip):

### Applying the filters

Once you have verified that your server is responding on port 28015/UDP and the game-server is functional we can go ahead and apply the application specific filter to fine-tune the protection for your server.

Proceed to head over to the **Filters** page on the left hand side of the portal page.

You should be directed to a page that looks similar to below:

Your Rust server is ready to go and is setup to best defend from attacks. If you have any issues or concerns with this setup feel free to reach out to us via the support!
