This demonstrates that by shutting down the SSH service, you can completely deny remote access. Instead of
blocking all access by stopping a service, you can selectively restrict remote access through the ESXi firewall.

Before creating the firewall rules to block SSH access, you have to first enable the SSH service as follows:
1. Click the Services Properties link, as shown in Figure 112.
2. Select SSH service in the Service Properties panel, as shown in Figure 117. You can see that the SSH service
