The DSL router is configured for NAPT using a single public IP address.
H
When using NAPT, the DSL (d0) interface must be numbered because the
Ethernet interface will be configured within the private address space.

NAPT static mapping is configured for a server (Telnet port 23) on the
Ethernet interface but publicly available.
The command line syntax is:
ifn address e0
ifn address d0
ip route create upstream e0 155.1.3.1
