(Optional) Configuring the Default Processing Mode for Unmatched Packets

(Optional) Configuring the Default Processing Mode for Unmatched Packets

Context

By default, a firewall allows all the outbound packets and denies all the inbound packets.

If an ACL is applied to the inbound or outbound packets in an interzone, the firewall filters packets according to the ACL rules. If packets do not match the ACL, the firewall uses the default processing mode for the packets.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run firewall interzone zone-name1 zone-name2

    The interzone view is displayed.

  3. Run packet-filter default { deny | permit } { inbound | outbound }

    The default processing mode for unmatched packets is configured.

    NOTE:

    When you are modifying filtering rules in an interzone, some sessions may not be filtered properly according to the rules. Therefore, after the modification is complete, use the reset firewall session all command to delete all existing firewall session entries.
