ICMP packets not showing up after successful DHCP

Hi,

I am working on VNFs for building a home router and currently stuck in the phase right after successfully acquiring IPv4 address from another router running pfSense. Following the protocol described in wiki: https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol I can see the respective DHCP DORA packets in wireshark running on another machine in the same LAN as the new home router. The topology is here.

The problem is that although the DHCP lease is visible in the pfSense no ICMP packets to the new router are ever seen by the host running Wireshark (monitoring all LAN traffic). However, psSense is able to ping the Wireshark host, and ICMP packets are visible in this case. I tried disabling the firewall in pfSense, still no change. Any ideas what is wrong in this situation?
