Router Gateway Port Forwarding Setup Failure - getting error "Please use only AlphaNumeric Characters"

Question

When trying to setup a Forwarded Port in the Router Gateway Application (login successful and all services functioning and identified), I choose connected device from the “Select a device to add IPv4 and IPv6 address” button… the fields are populated automatically by the Router program, and then I enter the port number in the start and end port boxes, then hit Save…

An Alert popup box appears with “Please use only alphanumeric characters”.

Even if I populate the boxes with manual keyboard entry, I receive the same result.

I have tried to use the mobile phone web GUI version of the Router Gateway, and receive the same result as I have described above (using the Computer CPU to add the new Port Forward service.

HELP?!

I ran a quick test and selected my laptop from the Connected Device button and both the IPv4 and IPv6 address populated. The ports I used for test was 407 and I was able to save the settings. Could you please answer the following questions to understand better.What is the Service name entered?What are the Internal and External Start/End port numbers that are entered?

Please try entering a Service name without spaces.
