Yes, you can access the user interface from your LAN or from the Internet.
Please note that remote access might require you to change your firewall
To access the user interface remotely you can use a web browser. To connect,
you need to type the URL of the GUI into the address bar. When you type the
URL (http://127.0.0.1:9501) on a remote computer, you must change the
"127.0.0.1" address, to the IP address (or the hostname) of the computer
where the Ozeki NG SMS Gateway is installed to. For example
you can type "http://220.127.116.11:9501/" if your Ozeki NG SMS Gateway is
installed to a computer that has an IP address of 18.104.22.168.
If you have a DNS server and you create a DNS "A" record that points to your
public IP address, you can use the DNS name. For
example if your DNS entry "smsgateway.mydomain.com" points to "22.214.171.124",
you can type http://smsgateway.mydomain.com:9501 into your webbrowser to access
the user interface of Ozeki NG SMS Gateway.
It might be possible, that you don't want to run the built in webserver of Ozeki
NG SMS Gateway on port 9501. In this case, you need to open the "Client
connectivity" tab of the "Edit/Server preferences" form in the Ozeki NG user
interface, and you need to change the port 9501. If you change this port to 80,
which is the default HTTP
port, you can access the Ozeki NG SMS Gateway's user interface without entering
a port number into the URL in your webserver. For example, you can type:
or http://126.96.36.199 or http://smsgateway.mydomain.com.
If the Ozeki NG login screen does not come up, the most probable reason, is
that your firewall is blocking remote access to port 9501 of the computer, where
the Ozeki NG SMS gateway is installed to.
