About Internet broadband connections
Connecting over the Internet to a home-based network that uses a broadband
solution such as a cable modem or DSL can present some challenges. Many
home-based broadband Internet solutions include a cable or DSL router, which
lets multiple computers share a single Internet connection. The router uses
Network Address Translation (NAT) technology to make this address sharing
possible.
In a sharing situation, this IP address is assigned to the router. The router, in turn,
generates new IP addresses, and then assigns them to the individual computers
that share the connection.
When you subscribe to a broadband service, your Internet service provider (ISP)
assigns you a single IP address. These router-assigned IP addresses are private
and cannot be seen from the Internet. The only address that can be seen from the
Internet is the IP address that is assigned to the router.
Figure 1-1 shows how Internet broadband connections are made.

To support inbound connections from a pcAnywhere remote, you must configure
the router to direct incoming data from the pcAnywhere ports to the
router-assigned IP address of the host computer.
For pcAnywhere connections, you must map the following pcAnywhere port
numbers to the private IP address of the host computer, which is assigned by the
router:
