4. DSL Router Configuration Examples
To enable Telnet through the service domain via the DSL router Ethernet (eth1) port, use the following commands:
telnet enable telnet login enable
telnet name create admin paradyne abc123

In this Basic NAT example:
NAT is used for
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.
