Ozeki NG SMS Gateway uses the http://127.0.0.1:9501 address. Can I change this to my IP address, so I can access it on my LAN or over the Internet?

Yes, you can change the 127.0.0.1 to point to your LAN or public IP address The IP address 127.0.0.1:9501 is not ours. This IP address allways points to the local computer you are working on. Every computer has two IP addresses the local 127.0.0.1 and a public IP address. The Ozeki software installed on your computer can be accessed on both IP addresses. For example if the public IP address of your computer is 192.168.1.100, you can access your Ozeki NG SMS Gateway service at http://192.168.1.100:9501 and http://127.0.0.1:9501 To sum it up you can change the 127.0.0.1 ip address to your computers IP address.  more
