Ethernet Link up, but Ping not working

Using NUCLEO-H723ZG without freeROTS for Ethernet. The link looks working since plugging and unplugging cable indicating "Link Up" and "Link Down". However, the Ping is not working. Not sure any functions need to be called after MX_LWIP_Init()? JYI

Whether LWIP responds to PING packets is a configuration option somewhere - lwipopts.h maybe?

Some people want to respond to pings, while others do not (for better security).
