Enabling MCP PING Commands through the EVLAN
Connection
Inbound Internet Control Message Protocol (ICMP) requests to the host of an environment
are blocked by default. This restriction affects PING commands, which are ICMP echo
requests. As a result, PING commands from remote computers cannot reach the host of
an environment, not even those sent from the MCP host.
To enable PING commands from the MCP to the I/O engine, create a customized firewall
rule to allow PING commands through the EVLAN connection, as follows:
1. Log on to the I/O engine environment using an account with Administrator privileges.
2. Start the Server Manager by clicking the Server Manager icon on the taskbar.
The Server Manager window is displayed.
3. On the left pane, expand the Configuration node, and then expand the Firewall
with Advanced Security node.
4. Right-click Inbound Rules and select New Rule.
The New Inbound Rule wizard starts and the Rule Type screen is displayed.
5. Select Custom and click Next.
The Program screen is displayed.
6. Select All Programs and click Next.
The Protocol and Ports screen is displayed.
7. Select ICMPv4 from the Protocol type list.
The Customize option under Internet Control Message Protocol (ICMP)
settings becomes available.
8. Click Customize.
The Customize ICMP Settings dialog box is displayed.
9. Select Specific ICMP types and Echo Request, and then click OK to save the
setting and exit the dialog box.
10. On the Protocol and Ports screen, click Next.
The Scope screen is displayed.
11. For the Local IP addresses, select These IP addresses, click Add, and type the
host EVLAN IP address, 192.168.16.6.
12. For the Remote IP addresses, select These IP addresses, click Add, and type the
MCP host EVLAN IP address, 192.168.16.5.
