Layer 3 forwarding devices exist between the authentication client and the access device, you must
select the cross-subnet portal authentication mode.
• In re-DHCP authentication mode, a client can use a public IP address to send packets before
passing portal authentication. However, responses to the packets are restricted.

Controlling access of portal users
204BConfiguring 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, source MAC
address, inbound interface, and VLAN. Packets matching a portal-free rule will not trigger portal
authentication, so users sending the packets can directly access the specified external websites.
383BConfiguration 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.
