Configuring Standard ACLs for Dynamic NAT
Configuring Standard ACLs for Dynamic
NAT
To configure dynamic translation, you use a standard ACL to select the IP addresses
that the Wireless Edge Services zl Module NATs. Although you can use any ACL
that you have configured, you will probably want to configure ACLs to meet the
specific requirements for your NAT implementation.
Remember that depending on the types of NAT you are configuring, you might need
to create several ACLs. If your module will NAT both inside and outside traffic, you
must create one ACL to select IP addresses used in the inside network and one ACL
that selects addresses used in the outside network.
To create ACLs, use the procedure documented in Chapter 7: “Access Control Lists
(ACLs).” For NAT, you must create a standard IP ACL.
To add rules to the ACL, use the screen shown in Figure 8-9.
