Specifying a Source Address for RADIUS and TACACS+ Servers

You can specify which source address the JUNOS software uses when accessing your network to contact an external TACACS+ or RADIUS server for authentication. You can also specify which source address the JUNOS software uses when contacting a TACACS+ server for sending accounting information.

To specify a source address for a TACACS+ server for authentication, include the source-address statement at the [edit system tacplus-server server-address] hierarchy level:



[edit system tacplus-server server-address]

source-address source-address;

source-address is a valid IP address configured on one of the router interfaces.

To specify a source address for a TACACS+ server for system accounting, include the source-address statement at the [edit system accounting destination tacplus server server-address] hierarchy level:



[edit system accounting destination tacplus server server-address]

source-address source-address;

source-address is a valid IP address configured on one of the router interfaces.

To specify a source address for a RADIUS+ server, include the source-address statement at the [edit system radius-server server-address] hierarchy level:



[edit system radius-server server-address]

source-address source-address;

source-address is a valid IP address configured on one of the router interfaces.

Note: You can configure the JUNOS software to select a fixed address as the source address for locally generated IP packets. For more information, see Configuring the Source Address for Locally Generated TCP/IP Packets.
