Figure 1. Firewall > Firewall Access > Ping Settings

Input field	Description
Allow IPv4 ping to firewall Allow IPv6 ping to firewall	Configure separately for IPv4 and IPv6 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 "Deny" by default, but you can change this to "Allow" if 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.
