Thanks, I have forwarded this port to my nano IP address and tested this to be working (this was tested using a port checking exe installed on my laptop on the same network, it said the port was open but that it was not able to ping the router tho it knew my external IP).
On trying to access this port using the external IP address (as per the format XX.XXX.XX.XXX:9080) from my phone it was unsuccesful.
has anyone else had this issue, and if so any solution?
the public IP address I used was from whatismyip.com
from the image I attached you can see that I have left the DNS and SMTP addresses as default, from the manual it doesn't sound as if this is necessary for this basic test?
