web-auth-server source from packet-destination-ip
Function
The web-auth-server source from packet-destination-ip command specifies the source IP address in the packets sent to the web authentication server as the destination IP address of the received packets.
The undo web-auth-server source from packet-destination-ip command restores the default configuration.
By default, the source IP address of the packets sent from the device to the web authentication server is not the destination IP address of the Portal packets received by the device.
This command is supported only on the NetEngine 8000 F1A.
Usage Guidelines
By default, when the BRAS interacts with the web authentication server, the BRAS searches for a route based on the VPN and destination IP address before sending packets to the web authentication server, and uses the IP address of the reachable interface of the route as the source IP address. If no route is found, the IP address of any interface in the VPN is used as the source IP address.
To ensure that the destination IP address of Portal packets received by the BRAS from the web authentication server is the same as the source IP address of Portal packets sent by the BRAS to the web authentication server, run the web-auth-server source from packet-destination-ip command. Configure the source IP address of the packets sent from the BRAS to the web authentication server as the destination IP address of the Portal packets received by the BRAS from the web authentication server.
