Basic NAT Configuration Example
In this Basic NAT example:
NAT is used for one-to-one mapping of addresses.
There are four private IP addresses configured on the Ethernet side of the
DSL router, with NAT static mappings to four public IP addresses.
The Ethernet interface (eth1) is in the private address space and the DSL
interface is in public address space.
The next hop router (default gateway) of the clients is the Ethernet IP address
of the DSL router, 10.1.3.1.
Since Basic NAT is enabled and the dsl1 interface address is on the same
subnet as the Basic NAT global IP network address, Proxy ARP must be
enabled on the DSL interface (dsl1). Proxy ARP is not necessary when using
FUNI/MPOA link encapsulation.
If IP Scoping is enabled, the client’s NAT mapping public IP addresses and the
dsl1 interface IP address must be entered into the client VNID table.
