In this DHCP Server with Basic NAT example:

HThe clients are using dynamic IP address assignment and use the Ethernet interface (eth1) of the DSL router as the next hop router (default gateway).

HThe DSL interface (dsl1) must be numbered.

HThe DSL router is configured as the DHCP server giving the private IP addresses to the clients.

HThe Ethernet interface is in private address space. NAT is used for one-to-one mapping of addresses.

The command line syntax for this example is:

ifn address eth1 10.1.3.10 255.255.255.240 ifn address dsl1 155.1.3.2 255.255.255.0 ip route create upstream eth1 155.1.3.1

nat basic address 192.128.1.0 nat basic enable
