My Windows server 2012 R2 which is also a passive copy of Exchange DAG has not been able to ping internet address like 22.214.171.124. The status of network adapter shows no internet access.
Windows Firewall for both domain/private/public disabled. Public IP for firewall uses same PAT interface for all servers and workstation and they are all working.
