Why can't I ping my Cloud VM?

By default ICMP traffic is blocked through the firewalls on our Cloud VM plans.  That means you will not get any response when trying to ping your VM IP address or a domain on the VM.  This would also affect other ICMP-based commands like traceroute.

If you want to open up your VM to allow ICMP traffic then you can either allow ICMP traffic with a Firewall rule or disable the firewall.

You make these changes in the Cloud Control Panel - you can reach the Firewall section as follows:

Virtual Machines > vm name > Networking > Firewall

OR

Virtual Machines > vm name > Tools > Edit Firewall Rules

Add Firewall Rule

Fill in the details as follows when in the Firewall panel:

• Interface: has to be eth0, your VM only has one network interface
• Command: Accept.
• Source Address: Leave blank for access from anywhere, or put in the IP address or netblock range in CIDR format that you want to open\block the 'ping' from.
• Destination Port: Leave blank.
• Protocol: ICMP.

Once done press Save and then 'Apply Firewall Rules'.

Note:

You may need to re-order the rule, typically to the top of the list, should there be another rule above this one which is blocking traffic -
See article below 'Changing the order of rules':

Disable Firewall

Follow these steps when in the Firewall panel:

Change the default command from DROP to ACCEPT > Save Rule  > Apply Firewall Rules

If doing this you should ensure you have a firewall installed on the VM itself first for security. The following may help you with that:
