Below is a diagram of a typical Radius systemintegration:
By default, the RADIUS server listens on the following ports:
| Port | Protocol | Function |
|---|---|---|
| 1812 | UDP | RADIUS authentication |
| 1813 | UDP | RADIUS accounting |
| 8090 | TCP |
...
| RADIUS management |
You will need to configure the local Windows firewall and network firewall to allow connections to these ports.
Windows Firewall Configuration
From the Server Manager window select "Tools | Windows Firewall with Advanced Security";
...
| Expand | ||
|---|---|---|
| ||
From the window titled "Windows Fiurewall with Advanced Security", Right click "Inbound Rules", then select "New Rule...";
A new window will open titled "New Inbound Rule Wizard" with subheading "Rule Type", we need to define inbound rules for all three of the ports, select "Port", then click "Next";
The sub-heading will now be updated to "Protocol and Ports", select "TCP". Select "Specfic local port", and enter a port value of "8090", then click "Next";. The sub-heading will now be updated to "Action", select "Allow the connection" then click "Next";
The sub-heading will now be updated to "Profile", select which profiles the rule applies to then click "Next";
The sub-heading will now be updated to "Name", provide a meaningful name and descriptions for the port that is being defined then click "Finish";

...
Once you have created all three inbound rules the firewall will be configured to allow the Radius server to listen for external connections.
