Step
2. Configure an
IPv4-based portal-free
rule.
3. Configure an
IPv6-based portal-free
rule.
To configure a source-based portal-free rule:
Step
1. Enter system view.
2. Configure a
source-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:
Command
portal free-rule rule-number
{ destination ip { ip-address
{ mask-length | mask } | any } [ tcp
tcp-port-number | udp
udp-port-number ] | source ip
{ ip-address { mask-length | mask } |
any } [ tcp tcp-port-number | udp
udp-port-number ] } *
portal free-rule rule-number
{ destination ipv6 { ipv6-address
prefix-length | any } [ tcp
tcp-port-number | udp
udp-port-number ] | source ipv6
{ ipv6-address prefix-length | any }
[ tcp tcp-port-number | udp
udp-port-number ] } *
Command
system-view
portal free-rule rule-number source
{ interface interface-type
interface-number | mac mac-address |
vlan vlan-id } *
144
Remarks
By default, no IPv4-based
portal-free rule exists.
By default, no IPv6-based
portal-free rule exists.
Remarks
N/A
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.
