ICMPv6

Internet Control Message Protocol for IPv6 (ICMPv6 or ICMP for IPv6) is defined in RFC 
4443. ICMPv6 has a preceding Next Header value of 58, which is different from the 
value used to identify ICMP for IPv4. ICMPv6 is an integral part of IPv6. IPv6 nodes use 
ICMPv6 to report errors encountered in packet processing and perform other diagnostic 
functions, such as "ping".

Respond to Ping on

The EMG2926-Q10A will not respond to any incoming Ping requests when Disable is 
selected. Select LAN to reply to incoming LAN Ping requests. Select WAN to reply to 
incoming WAN Ping requests. Otherwise select LAN&WAN to reply to all incoming LAN 
and WAN Ping requests.
