2. Configure a
destination-based
portal-free rule.

Configuring an authentication source subnet

By configuring authentication source subnets, you specify that only HTTP packets from users on the
authentication source subnets can trigger portal authentication. If an unauthenticated user is not on
any authentication source subnet, the access device discards all the user's HTTP packets that do not
match any portal-free rule.
When you configure a portal authentication source subnet, follow these restrictions and guidelines:
•
Authentication source subnets apply only to cross-subnet portal authentication.
•
In direct or re-DHCP portal authentication mode, a portal user and its access interface
(portal-enabled) are on the same subnet. It is not necessary to specify the subnet as the
authentication source subnet. If the specified authentication source subnet is different from the
access subnet of the users, the users will fail the portal authentication.
In direct mode, the access device regards the authentication source subnet as any source

IP address.
In re-DHCP mode, the access device regards the authentication source subnet on an

interface as the subnet to which the private IP address of the interface belongs.
•
If both authentication source subnets and destination subnets are configured on an interface,
only the authentication destination subnets take effect.
•
You can configure multiple authentication source subnets. If the source subnets overlap, the
subnet with the largest address scope (with the smallest mask or prefix) takes effect.
To configure an IPv4 portal authentication source subnet:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv4 portal
authentication source
subnet.
To configure an IPv6 portal authentication source subnet:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 portal
authentication source
subnet.
