Access phpmyadmin via Internet (not intranet)

[tanthiamhuat]

I am able to access my webserver from another PC on the same network as the webserver (192.168.1.xxx), using http://192.168.1.xxx/phpmyadmin

However, I would also want to access that webserver (192.168.1.xxx) from another PC, outside the network as the webserver, via internet. Is that possible? Which portion of the config.inc.php file would I need to modify?

I understand that there would be some security issues. How would we take care of that?
