The reason blocking pings prevents the IP address change is because a lot of DHCP servers ping the IP before they (re)allocate the address. If the device responds to the ping then the DHCP server abandons the IP and leases a new one.

For this reason the network stack should; in my opinion ignore IPv4 ICMP echo requests during the DHCP part of the roam process. Indeed I believe that this was the behaviour previously.

Blocking IPv4 pings isnt impacting any other functionality for me.
