Configuring ICMP Access
Guidelines and Limitations
This section includes the guidelines and limitations for this feature.
Context Mode Guidelines
Supported in single and multiple context mode.
Firewall Mode Guidelines
Supported in routed and transparent firewall mode.
IPv6 Guidelines
Supports IPv6.
Additional Guidelines
• The ASA does not respond to ICMP echo requests directed to a broadcast address.
• The ASA only responds to ICMP traffic sent to the interface that traffic comes in on; you cannot
send ICMP traffic through an interface to a far interface.
• If you cannot ping the ASA interface, make sure that you enable ICMP to the ASA for your IP
address using the icmp command.
Default Settings
By default, you can send ICMP packets to any ASA interface using either IPv4 or IPv6.
