A company has a Palo Alto Networks firewall with multiple virtual routers. The security policy has a rule that allows SSH from the 'Internal' zone to the 'DMZ' zone. Recently, a new subnet 10.10.20.0/24 was added to the Internal zone. Users in that subnet report they cannot SSH to a server at 192.168.1.10 in the DMZ, while users from other subnets in Internal can. The rule has source address object '10.0.0.0/8' which includes the new subnet. The rule's source zone is Internal, destination zone is DMZ, and application is SSH.
