Port Forwarding for ICMP / Ping, without 1:1?



  • Is there a way to port-forward Ping without a 1:1 mapping?

    There is no ICMP protocol choice under the Port Forwarding section.

    Apparently I am forced to do a full "1:1 NAT" 65536-port mapping if I want just HTTP and PING to work from the WAN?

  • Either 1:1 ,or have the firewall answer the ping. 1:1 doesn't necessarily forward everything, it's controlled by firewall rules.

    Another note:

    On 2.1, there is an ICMP choice in the protocol list for port forwards.
