Configuring a portal-free rule

A portal-free rule allows specified users to access specified external websites without portal authentication.

The matching items for a portal-free rule include the source and destination IP address, TCP/UDP port number, source MAC address, inbound interface, and VLAN. Packets matching a portal-free rule will not trigger portal authentication, so that users sending the packets can directly access the specified external websites.

For Layer 2 portal authentication, you can configure only a portal-free rule that is from any source address to any or a specified destination address. If you configure a portal-free rule that is from any source address to a specified destination address, users can access the specified address directly, without being redirected to the portal authentication page for portal authentication. Usually, you can configure the IP address of a server that provides certain services (such as software upgrading service) as the destination IP address of a portal-free rule, so that Layer 2 portal authentication users can access the services without portal authentication.

Follow these guidelines when you configure a portal-free rule:

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.
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.

To configure a portal-free rule:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Configure a portal-free rule.	To configure an IPv4 portal-free rule:portal free-rule rule-number { destination { any \| ip { ip-address mask { mask-length \| netmask } \| any } [ tcp tcp-port-number \| udp udp-port-number ] } \| source { any \| [ interface interface-type interface-number \| ip { ip-address mask { mask-length \| mask } \| any } [ tcp tcp-port-number \| udp udp-port-number ] \| mac mac-address \| vlan vlan-id ] * } } * To configure an IPv6 portal-free rule:portal free-rule rule-number { destination { any \| ipv6 { ipv6-address prefix-length \| any } } \| source { any \| [ interface interface-type interface-number \| ipv6 { ipv6-address prefix-length \| any } \| mac mac-address \| vlan vlan-id ] * } } *	Configure at least one command.

NOTE:

Regardless of whether portal authentication is enabled or not, you can only add or remove a portal-free rule. You cannot modify it.
