Symantec PCANYWHERE - V12.1, User Manual

Page: 25 / 321

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:
■
5631 (data)
■
5632 (status)
If you are connecting to a host computer that uses custom port numbers, you
must configure the custom port numbers in the remote connection item. This
port mapping configuration is done in the administrator properties for the router,
which is typically accessible through a Web browser. The location of the port
mapping settings varies by router.
For more information, consult the documentation for your router.
Symantec pcAnywhere Gateway lets you set up a single connection point to
facilitate the process of finding and connecting to host computers that are behind
a Network Address Translation (NAT) device.
See “About Symantec pcAnywhere Gateway” on page 301.
About connecting from outside a firewall
For security reasons, an administrator might set up a firewall to restrict access
to specific IP addresses. A firewall prevents computers that are outside the firewall
from connecting to any IP address that is inside the firewall. Some corporate
environments might also have security policies that restrict users from installing
a modem phone line behind a firewall.
If the host computer is connected to a network that is behind a firewall, the remote
user must have a way to connect to the network through a Remote Access Service
(RAS) or virtual private network (VPN). This information must be provided by an
administrator.
Once the remote user connects to the corporate network using one of these trusted
services, the remote computer becomes a node on the network and can use
pcAnywhere to connect to the target computer using TCP/IP.
Connecting to a network host computer from outside a firewall involves the
following process:
■
Connect to the host site's network using the procedures provided by the
administrator at the host site.
