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.
■
In pcAnywhere, configure a TCP/IP network connection, specifying the IP
address of the host computer to which you want to connect.
See “Configuring a remote network connection” on page 101.
■
Start the remote control session.
See “Ways to start a remote control session” on page 115.
