# Configure domain dm1 as the default ISP domain for all users. Then, if a user enters a username
without any ISP domain at logon, the authentication and authorization methods of the default
domain are used for the user.

3. Configure portal authentication:
# Configure the portal server as follows:
{ Name: newpt
{ IP address: 192.168.0.111
{ VPN: vpn3
{ Key: portal, in plain text
{ Port number: 50100
{ U R L : h t t p : / / 19 2.16 8 . 0 .111:8080/portal
[RouterA] portal server newpt ip 192.168.0.111 vpn-instance vpn3 key simple portal
port 50100 url http://192.168.0.111:8080/portal
# Enable Layer 3 portal authentication on the interface connecting the user side.
[RouterA] interface ethernet 1/1
[RouterA–Ethernet1/1] portal server newpt method layer3
[RouterA–Ethernet1/1] quit

Troubleshooting portal
Inconsistent keys on the access device and the portal server
Symptom
When a user is forced to access the portal server, the portal server displays a blank Web page, rather
than the portal authentication page or an error message.
Analysis
The keys on the access device and those on the portal server are not configured consistently, causing
CHAP message exchange failure. As a result, the portal server does not display the authentication page.
