Hi,
This is by design. ICMP (ping) is legitimate protocol. In this case it is
used to determine if other DCs are up and running. It is also used to
determine link speed etc. If you close ICMP traffic between two DCs
replication of group policies will fail. There are also known problems with
you close ICMP between client and DC.
