Testing Remote Connections

Ping and Traceroute are tools that send simple messages to an IP address to test the

connection between the device sending the message and the device with the given IP.

• Ping sends the message and waits for a reply. If a reply is received, we know the device

with the given IP is running and can receive and transmit data. Using Ping, you can

check whether your MVG 400 unit is running and can be accessed remotely.

• Traceroute sends the message and follows the route it takes from machine to machine in

the network to reach its destination. This may help you identify routing problems or

firewalls that are interfering with remote connections to your MVG 400.

NOTE: Some devices are configured not to respond to Ping requests. Therefore, the fact

that a device does not respond to a Ping request does not prove unequivocally that

the device cannot be accessed remotely. Similarly, since Traceroute makes use of

Ping, the information returned by Traceroute may be incomplete.

Both Ping and Traceroute are available from any Windows Command Window. You can use

them from Windows to test connections from the PC to other devices, such as the MVG 400.

This is useful as an initial diagnostic tool in a situation in which you can connect to the

MVG 400 unit for configuration and client access through a PC that is on the same LAN as

the unit, but you cannot connect to the unit remotely.

You can run also Ping and Traceroute from the MVG 400 configuration utility to test

connections from the MVG 400 to other devices, such as SMS / SMTP servers and NTP

servers.

Ping

Ping is a tool that sends a simple message to an IP address and waits for a reply. If a reply is

received, we know the device with the given IP is running and can receive and transmit data.

Ping is available from any Windows Command Window. Using Ping from a remote PC, you

can check whether your MVG 400 unit is running and can be accessed remotely. You can also

test remote connections from the MVG 400 unit to other devices by running Ping from the

configuration utility.
