Check the following:
- Check that the device is correctly powered up (status LED is green) and plugged into the network (network LED is green).
- If the status LED is showing a problem perform a power cycle, and if there is still a problem restore the factory settings.
- Make sure the device is listed as online and installed in Boost.LAN Manager.
(If not see the FAQ: I can’t find my ES device in Boost.LAN Manager)
- Make sure that the port you are trying to open is not being blocked by a firewall or anti-virus that may be installed. (see Firewall FAQ)
