Configuring ACL Rules

Configuring ACL Rules

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run acl [ number ] acl-number [ match-order { auto | config } ]

    An ACL with the specified number is created and the ACL view is displayed.

  3. Configure basic or advanced ACLs as required. For details, see Configuring a Basic ACL or Configuring an Advanced ACL in the Huawei AR Series V200R010 Configuration Guide - Security - ACL Configuration.

    NOTE:

    Only basic ACLs (2000 to 2999) and advanced ACLs (3000 to 3999) can be used to configure the NAT function.

    1. When permit is used in the ACL rule, the system uses the address pool to translate addresses for the packets of which the source IP address is specified in the ACL rule.

    2. When permit is not used in the ACL rule, the NAT policy referencing the ACL does not take effect. That is, the system searches routes for packets, but does not translate addresses.

    3. If the ACL rule referenced in the command is modified, the modification does not take effect immediately. To make the modification take effect immediately, run the reset nat session command to clear the mapping entry information. You are advised not to modify the ACL rules in use.
