Firewall Rules
Sonoran Shield allows you to easily lock down unused ports, restrict access based on IPs, and more!
Open and unused ports represent potential security vulnerabilities. Attackers can exploit open ports to gain unauthorized access to a system, take down your server through denial of service attacks (DoS/DDoS) and compromise its security. By blocking unused ports, organizations can reduce their attack surface and minimize the risk of a successful attack. It is a best practice to only allow traffic on necessary ports to limit potential vulnerabilities and maintain the security of the system.
Sensitive ports can be limited to only authorized source IP addresses (your developers for example) to limit attack surface further while allowing access to authorized users.

The first rule will block access on all unused ports. After this, we will add rules to open only the ports we need.
- Select
New Rule
- Add your server's IP address in the
Destination
drop-down - Select
Network
as theSource Type
- Set the
Source IP
to0.0.0.0/0
- Leave the
Protocol
,Source Port
, andDestination Port
fields blank - Set the
Action
toBlock
- Save the new rule

Next, we will want to open up a port for remote desktop connections. This will allow us to use Window's RDP to view/manage our server.
- Select
New Rule
- Add your server's IP address in the
Destination
drop-down - Select
Network
as theSource Type
- Set the
Source IP
to:- Allow any IP:
0.0.0.0/0
- Or, allow only your specific IP address to connect
- Set
Protocol
toTCP
- Leave the
Source Port
field blank - Set the
Destination Port
to 3389- This is the default RDP port for Windows servers
- Set the
Action
toAllow
- Save the new rule
Continue this process to open additional ports for your game server and any other applications.
