Configuring Source NAT to Dynamic VLAN Address
When a VLAN interface obtains an IP address through DHCP or PPPoE, a NAT pool (dynamic-srcnat) and a
session ACL (dynamic-session-acl) are automatically created which reference the dynamically-assigned IP
addresses. This allows you to configure policies that map private local addresses to the public address(es)
provided to the DHCP or PPPoE client. Whenever the IP address on the VLAN changes, the dynamic NAT pool
address also changes to match the new address.
For example, the following rules for a guest policy deny traffic to internal network addresses. Traffic to other
(external) destinations are source NATed to the IPaddress of the DHCP/PPPoE client on the controller.
