Configuration guidelines
• If you specify both a VLAN and an interface in a portal-free rule, the interface must belong to the
VLAN. Otherwise, the rule does not take effect.
• You cannot configure two or more portal-free rules with the same filtering criteria. Otherwise, the
system prompts that the rule already exists.
• Regardless of whether portal authentication is enabled or not, you can only add or remove a
portal-free rule. You cannot modify it.
• A Layer 2 interface in an aggregation group cannot be specified as the source interface of a
portal-free rule, and the source interface of a portal-free rule cannot be added to an aggregation
group.
Configuration procedure
To configure a portal-free rule:

1. Enter system view.

2. Configure a portal-free
rule.

{ mask-length | mask } | any } [ tcp tcp-port-number [ to tcp-port-number ] |
udp udp-port-number [ to udp-port-number ] ] } | source { any | [ interface
interface-type interface-number | ip { ip-address mask { mask-length | mask }

udp-port-number ] ] | mac mac-address | vlan vlan-id ] ] * } } *
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.
Configuration of authentication source subnets applies to only cross-subnet authentication. In direct
authentication mode, the authentication source subnet is 0.0.0.0/0. In re-DHCP authentication mode,
the authentication source subnet of an interface is the subnet to which the private IP address of the
interface belongs.
If both an authentication source subnet and destination subnet are configured on an interface, only the
authentication destination subnet takes effect.
