Allow / Deny
The built-in firewall can prevent unauthorized logins and control services accesses. In addition, you can choose to allow or deny the access to certain network ports from specific IP addresses.
To create a firewall rule:
- Go to Control Panel > Firewall and select the network interface from the left column according to the type of your network connection.
- Click Create.
- In the Ports section, select one of the followings for the rule:
- Choose All to apply the rules to all ports.
- Choose Select from a list of built-in applications.
- Choose Custom and click Custom, and then enter up to 15 ports separated with comma, or specify a port range.
-
You can also specify the protocols.
- In the Source IP section, select one of the followings for the rule:
- Choose All to allow or deny all IP addresses.
- Enter a Single host IP address.
- Enter a Subnet.
- In the Action section, select one of the followings for the rule:
- Choose Allow to allow the access meeting the ports and source IP settings above.
- Choose Deny to deny the access meeting the ports and source IP settings above.
Now you can see the created firewall rule in the rule list.
To delete firewall rules, do any of the followings:
- Uncheck the checkbox of the rule in the Enabled column of the list
- Delete the firewall rule
You can also choose to Allow access or Deny access at the bottom of the rule list to allow or deny the access that matches no rules.
Note:
- You can create up to 100 rules for a network interface, and you can reorder the rules in the list by drag-and-drop.
- The rules are prioritized according to their positions in the list.
- If your system has 2 network ports connecting to the same subnet, the firewall rules may not work properly.*
