Users external to the network need to connect to the IP address of the router, not your computer's internal IP address. If port forwarding is then correctly configured for your router, that should then work to connect a web browser to your database.
A web site such as WhatIsMyIP can show you the correct IP address.
Many thanks for the response Phil.
Still having problems even with that, and having forwarded respective ports and ip addresses.
Trying the DNS route at the moment to see if viable alternative.
Thanks again for your help...
At my wits end with it, and here's me thinking it was an easy set up.
I've tried every configuration, forwarding, deleted and reloaded... cannot waste any more hours on this so gonna dump it for what it's worth.
Really appreciate your help but I'm done.
