n Mode = NAT
n Trusted IP address = 10.1.1.1
n Alternate destination port = 8080
l External captive-portal server 2:
n Name = external_cp2
n Mode = NAT
n Trusted IP address = 10.1.1.2
l External captive-portal server 3:
n Name = external_cp3
n Mode = NAT
n Trusted IP address = 10.1.1.3
l Health-check ping:
n Name = externalcp_ping
n Frequency = 30 seconds
n Retry-count = 2 attempts
n Timeout = 2 seconds (2 seconds is the default)
l ESI group = external_cps

Configuring the Example NAT-mode ESI Topology
This section describes how to implement the example NAT-mode ESI topology shown in using both the WebUI,
then the CLI.
The configuration process consists of these general tasks:
l Configuring captive portal (see the “Configuring Captive Portal” chapter).
l Configuring the health-check ping method.
l Configuring the ESI servers.
l Configuring the ESI group.
l Defining the redirect filter for sending traffic to the ESI server.
Configuring the NAT-mode ESI Example in the WebUI
Navigate to the Configuration > Advanced Services > External Services view on the WebUI (see ).
In the WebUI
