Mikrotik Router OS – Installation and Configuration for Aradial and Spotngo.

Sample Network deployments
Centralized Deployment:
Typical Deployments: Hotspot service Providers, ISP, WISP, VOIP, Corporate, hosted solution,
etc.
Aradial and Spotngo Payment Module are installed at the NOC, Network Operation Center, Data
Center, Hosted environment or Head office.
Mikrotik gateway / Access controller (Network Access Server) installed on site at internet point of
presence.
Client redirection and AAA Radius requests will be sent by the Mikrotik unit to the centralized
Radius server and billing solution for processing.

Notes:
Hotzones are located at a different geographical location each
with their own internet connection. Access controllers will perform
the AAA (Authentication, Authorization and Accounting) through
the centralized Aradial Server.
The network further supports roaming, and custom branding per
location, dealers and affiliates.
Aradial Radius server can be deployed in a redundant – high
availability.
Supports a wide range of access controller and access points.

Note:
1. The check mark on the side of the setting means NOT (!), if checked the rule will apply to
all other hotspot except hotspot1.
2. For website URL or redirection using URL and SSL Certificate such as:
https://secure.aradial.com , Use the Dst. Host instead of Dst. Address for example:

External Captive portal redirection:
The Mikrotik internal Captive Portal can be replaced with an External captive portal redirection.
On the side menu go to files, and replace the login.html file under the hotspot directory with a new
login.html containing the following redirect code. This can be accomplished by removing the
original login.html from the /hotspot/login.html (Highlight it and click the Minus button (-) to remove.
Page 24

Then drag the newly created login.html from your desktop and drop it under the hotspot directory.
The file will reposition itself to /hotspot/login.html.
Login.html for Spotngo Payment Module portal:

Aradial URL Redirection links:
Depending on your Aradial Installation and configuration, you can deploy the portal using Aradial
built in web servers, Windows IIS or others.
Please see the most common URL deployments below:
Aradial Portal – Aradial web server: http://192.168.8.34:8002/Portal?AP=MT
Aradial Portal – Windows IIS server: http://192.168.8.34/ardweb/ardadminis.dll?AP=MT
Spotngo – Spotngo Web server: https://r01.spotngo.net/Payment?AP=MT
Spotngo Portal – Windows IIS server: http://192.168.8.34/ardweb/SPNGPaymentis.dll?AP=MT
Location Branding:
Both Aradial and Spotngo Captive Portals support location branding and the parameter can be
entered in the login.html redirect URL to identify the calling location and price groups.
The following Portal identity should be sent with the redirection:
&Portal=Location-Subdirectory, where the Location- subdirectory refers to the branding
subdirectory under the Portal folder.
For Example:
Aradial Portal – Windows IIS server:
http://192.168.8.34/ardweb/ardadminis.dll?AP=MT&Portal=Example1
Mikrotik Login Portal Error Display:
Both Aradial and Spotngo Portals can display the Mikrotik login errors when redirecting client to
the portal following a portal login error.
To instruct the MikroTik to send the Error message to the Portal, please add &MT_Error=$(error)
to the redirect URL:
For example:
Aradial Portal – Windows IIS server with portal branding and login error display:

http://192.168.8.34/ardweb/ardadminis.dll?AP=MT&Portal=Example1&MT_Error=$(error)

Additional Status page is available including the persistent popup window.
Please let us know and we can send it to you.
Trouble shooting Portal Redirection:

If the MT did not do a captive portal redirection then it could be one of the following reasons:
1. IF the DNS does not resolve, the MikroTik hotspot does not know if the user is allowed to go to
the destination/url requested, then will not know if the allow through or block access and redirect
to the portal.

Symptom: The URL in the browser will still point to the original requested URL. Most likely
with page cannot be displayed.
Possible Cause: Check to make sure the DNS servers primary and secondary are configured
properly in the Mikrotik. And make sure your PC received a DNS from the MikroTik.

2. IF the MikroTik is attempting to redirect:
Symptom: If the url changes to wireless.aradial.com/login. Or the hotspot local DNS NAME:
Possible Cause: Check the redirection login.html file on the MikroTik and make sure it is
under /hotspot/login.html

Symptom: If the url changes to Aradial IP / URL but page does not load.
Possible Cause: Check:
- The IP >> Hotspot >> Walled Garden IP List has a rule to accept traffic to the Aradial
Server IP Address and / or URL.
- Aradial portal is reachable from outside the server on that URL. And that no firewall is
blocking access to the service.
