Ping Settings

The Ping Settings allow you to specify how your LANCOM R&S^®Unified Firewall handles ICMP echo requests (ping) to the firewall from the internal network and the Internet.

Navigate to Firewall > Firewall Access > Ping Settings to open an editor panel to display and edit the ping settings.

Input field	Description
Ping (ICMP to Firewall)	Select the respective radio button to specify how your LANCOM R&S^®Unified Firewall handles ICMP echo requests to the firewall from the internal network and the Internet. The option is set to `Allow` by default, but you can adjust the settings to the other value as required: `Deny` – The LANCOM R&S^®Unified Firewall does not respond to ICMP echo requests to the firewall from the internal network and the Internet. `Allow` – The LANCOM R&S^®Unified Firewall reponds to ICMP commands to the firewall from the internal network and the Internet. Important: While blocking ICMP echo requests can improve the security of your LANCOM R&S^®Unified Firewall, it also makes any troubleshooting in the network difficult. Therefore, if an error occurs in the network, we recommended setting this option to `Allow` before you start troubleshooting.
