Open
a port in the firewall
Almost all
companies protect their network by a firewall.
This firewall is only open for a very few things
or ports like HTTP (Web-server) and SMTP (e-mail).
The Remote
Server application is a TCP/IP based server
accepting a configurable TCP/IP port number (default
port number is 2000) .
The IT-department
could open the current port number (e.g. 2000)
for IP traffic directed directly to the Remote
Server therby making it reachable from the
Internet. This is possible because the Firewall
will convert the port number to an internal IP
address on the Intranet (NAT). In addition it
might be possible to configure the firewall so
that only acceptable IP-adresses (callers) can
use the specific port.
Note that
service providers (callers) will probably need to
ask their IT-department to open for the port to
be opened for communication out of their network.
This solution
gives a high level of certainty that no misuse of
the company network can be done. An extra global
IP address is NOT needed.
Note that if
you have multiple Remote PC's, each will need a
specific port.
Note that there
is no protection against users that have a Remote
client application.
