Applying a Rust game firewall rule and filter

In this article we will be discussing a quick and simple method of securing and setting up your firewall to whitelist and protect your Rust game-server. Please direct yourself to your filtering/firewall portal and login with the credentials you were providing during onboarding.

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

    51.79.45.167

    142.44.175.123

    167.114.219.233

    51.222.127.205

    51.222.127.206 

    51.222.127.207 

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:

We will be making two filters, both a VSE as well as a RakNet v2 filter. As an addition you may also want to apply the TCP Symmetric Filter  (assuming you route traffic symmetrically through us) to the Rust+ app port, as well as applications such as SSH/RDP for further protection.

See the images below on applying the VSE as well as the RackNet v2 filters:

Complete! 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 desk!
