Packet Filters > ICMP
Packet Filter > ICMP
ICMP (Internet Control Message Protocol) is used to test the network connections and the functionality of the
RouteFinder. It is also used for diagnostic purposes.
ICMP-on-Firewall and ICMP Forwarding always apply to all IP addresses (Any). When these are enabled, all
IP hosts can PING the RouteFinder (ICMP-on-Firewall) or the network behind it (ICMP Forwarding). Unique
IP addresses can then no longer be ruled out with packet filter rules. If the ICMP settings are disabled,
separate IP hosts and networks can be allowed to send ICMP packets through the RouteFinder firewall by
using appropriate user defined packet filter rules.
Screen Notes: The RF830/RF830-AP screen includes a field for ICMP on WAN2.
With the AP build, an additional screen option for ICMP on WLAN displays.
