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.

In the WebUI

1.Navigate to the Configuration > Security > Access Control > Policies page. Click Add to add the policy guest.

2.To add a rule, click Add.

a.For Source, select any.

b.For Destination, select network and enter 10.1.0.0 for Host IP and 255.255.0.0 for Mask.

c.For Service, select any.

d.For Action, select reject.

e.Click Add.

3.To add another rule, click Add.

a.Leave Source, Destination, and Service as any.

b.For Action, select src-nat.

c.For NAT Pool, select dynamic-srcnat.

d.Click Add.

4.Click Apply.

In the CLI

(host) (config) #ip access-list session guest any network 10.1.0.0 255.255.0.0 any deny any any any src-nat pool dynamic-srcnat

Configuring Source NAT for VLAN Interfaces

The example configuration in the previous section illustrates how to configure source NAT using a policy that is applied to a user role. You can also enable source NAT for a VLAN interface to cause NAT to be performed on the source address for all traffic that exits the VLAN.

Packets that exit the VLAN are given a source IP address of the “outside” interface, which is determined by the following:

•If you configure “private” IP addresses for the VLAN, the controller is assumed to be the default gateway for the subnetwork. Packets that exit the VLAN are given the IP address of the controller for their source IP address.

•If the controller is forwarding the packets at Layer-3, packets that exit the VLAN are given the IP address of the next-hop VLAN for their source IP address.
