3. Configure portal authentication on the SecPath:
# Configure the portal server as follows:
{
Name: newpt
{
IP address: 192.168.0.111
{
Key: portal
{
Port number: 50100
{
URL: http://192.168.0.111:8080/portal.
[SecPath] portal server newpt ip 192.168.0.111 key portal port 50100 url
http://192.168.0.111:8080/portal
# Configure the SecPath as a DHCP relay agent, and enable the IP address check function.
[SecPath] dhcp enable
[SecPath] dhcp relay server-group 0 ip 192.168.0.112
[SecPath] interface gigabitethernet 0/2
[SecPath–GigabitEthernet0/2] ip address 20.20.20.1 255.255.255.0
[SecPath–GigabitEthernet0/2] ip address 10.0.0.1 255.255.255.0 sub
[SecPath-GigabitEthernet0/2] dhcp select relay
[SecPath-GigabitEthernet0/2] dhcp relay server-select 0
[SecPath-GigabitEthernet0/2] dhcp relay address-check enable
# Enable re-DHCP portal authentication on the interface connecting the host.
[SecPath–GigabitEthernet0/2] portal server newpt method redhcp
[SecPath–GigabitEthernet0/2] quit
Configuring cross-subnet portal authentication
Network requirements
As shown in Figure 119 :
• SecPath A is configured for cross-subnet portal authentication. Before passing portal authentication,
a user can access only the portal server. After passing portal authentication, the user can access
Internet resources.
• The host accesses SecPath A through SecPath B.
• A RADIUS server serves as the authentication/accounting server.
