I have a program that I want to use called orbit downloader. But
after reading articles on the web, I noted that it has a "phone
home" behavior to a specific IP address. This might be nothing at
all. None of the articles that I read noted any suspicious behaviour
or spyware with this program. I just do not like ANYTHING that
connects to an IP address unless I manually tell it to do so.

I have a linksys wgrt Wireless G router. I know how to allow
INCOMING addresses. I know how to restrict INTERNAL ip addresses
from getting OUT of the network. But how do I restrict any internal
machine from contacting a SPECIFIC IP address, but allow it to
contact others. I really do not want to run a software firewall just
on this one machine. Since I only have a 2 machine network and the
firewall in the WGRT does just fine.

After reading the docs in the router's pdf file, all I could find is
how to block contacts to specific PORTS, or how to block INTERNAL IP
Addresses from using specific ports.

Before you ask I do not know which port that program tries to
contact at that address. The article only listed the IP address that
the program tries to contact not the port. AND NO I have not run the
program yet and done a netstat. I would like to find out how to
block contact to that ip address even before I run the program.

Thanks and I hope this is clear enough
