Service-based remote control like GoToMyPC and LogMeIn do not require
inbound ports open because they call out to a server.
Webex does too, but I agree with the others that it would be overkill for a
remote control application; however if you are already paying for Webex.com
account that sits idle or underused you might be able to use the idle time.
Note however that a Webex session must be manually started on the controlled
computer, which rather defeats the whole idea.
VNC works fine, but now that the Windows XP Remote Desktop Connection is
available and built in, VNC is a much less attractive proposition. I have
found that I could use VNC where RDC would not work, as with very low
bandwidth (24k) dialup connections, or when all I had was for the client
side was Java support in a browser in a locked down system, but under normal
circumstances RDC is more convenient. If you use VNC, because the VNC
traffic is normally unencrypted, at the very least you should use the
UltraVNC variant with built-in encryption or go through the hoops of setting
up an encryption server, which is a pain. Without the encryption of UltraVNC
a man in the middle could, at least in theory, recognize the signature of
VNC traffic, start listening, and extract keystroke information. Also, of
course, VNC requires opening an inbound port with forwarding on the
firewall. You can increase security a notch by using a very strong password
and by remapping remap to avoid the well known VNC ports. If you want to
control more than one machine, you have to do it anyway to redirect an
inbound port to each machine.
