By default, no IPv6-based
portal-free rule exists.
To configure a source-based portal-free rule:
1. Enter system view.

source-based
portal-free rule.

By default, no source-based
portal-free rule exists.
If you specify both a VLAN and an
interface, the interface must belong
to the VLAN. Otherwise, the
portal-free rule does not take effect.
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.
ï‚¡ In direct mode, the access device regards the authentication source subnet as any source
IP address.
