Creating and using firewall rules
Firewall rules allow you to control IP traffic. Use firewall rules to allow or drop IP traffic based on IP
addresses and services.
Enter up to ten rules, each rule specifying the host addresses, services, and the action to take for those
addresses and services.
Create a firewall rule
1. Open the Embedded Web Server.
2. Click the Settings tab, then Firewall Rules.
3. Click New, and then follow the onscreen instructions.
NOTE: After you click Apply, the connection to the Embedded Web Server might be temporarily
disrupted for a short period of time. If the IP address was unchanged, the Embedded Web Server
connection will be enabled again. However, if the IP address was changed, use the new IP address to
open the Embedded Web Server.
Change the priority of firewall rules
1. Open the Embedded Web Server.
2. Click the Settings tab, then Firewall Rules Priority.
3. Select the priority from the Rule Precedence list, with 10 having the highest priority and 1 having
the lowest priority.
4. Click Apply.
Change firewall options
1. Open the Embedded Web Server.
2. Click the Settings tab, then Firewall Options.
3. Change whatever options you wish, then click Apply.
NOTE: After you click Apply, the connection to the Embedded Web Server might be temporarily
disrupted for a short period of time. If the IP address was unchanged, the Embedded Web Server
connection will be enabled again. However, if the IP address was changed, use the new IP address to
open the Embedded Web Server.
