Configure Custom RADIUS Ports

The RADIUS authentication ports 1645, UDP, and 1812, UDP, on the RSA Authentication Manager server are open by default. You can configure custom RADIUS ports or multiport configurations for RSA RADIUS. You can specify as many as 256 RADIUS ports.

You can configure the same ports for both the IPv4 and the IPv6 interfaces.

Procedure

  1. Log on to the Operations Console on the RSA Authentication Manager instance hosting the RADIUS server.
  2. Click Deployment Configuration > RADIUS Servers.
  3. If prompted, enter the Super Admin User ID and password, and click OK.
  4. Select the RADIUS server that you want to update, and select Manage Server Files from the context menu.
  5. On the Manage Server Files page, select the default file, and select Edit from the context menu.

    To configure custom ports, modify the value of "port =" for both the IPv4 (ipaddr = *) and IPv6 (ipv6addr = ::) listen blocks.

    For a multiport configuration, add a new listen block. In the following examples, NEW_PORT is any valid port that is added for either interface.

    The following example adds a port for the IPv4 interface:

    listen {

    type = auth
    ipaddr = *
    port = NEW_PORT
    proto = udp

    limit {
    max_connections = 16
    lifetime = 0
    idle_timeout = 30
    }
    }

    The following example adds a port for the IPv6 interface:

    listen {

    type = auth
    ipv6addr = ::
    port = NEW_PORT

    limit {
    max_connections = 16
    lifetime = 0
    idle_timeout = 30
    }
    }

  6. Click Save.
  7. Click Save & Restart RADIUS Server for the changes to take effect.

After you finish

Repeat the edits on the other RADIUS servers in the deployment. To choose another RADIUS server, click the name of the currently selected RADIUS server, and click Back to List of RADIUS Servers.
