Hello,
Well i'm very new to this prgram but it seems to be exactly what i need. I'm having troulb with the connection part, here is my situation.

I have a computer at work, on a network, that i want to control from home. On the work computer i have windows 2000 professional, and at home i have XP home. I have installed the latest version of ultra VNC on both computers today (v 1.0.0 from the sourceforge website). At work i have the VNC server running. Now at home i open the viewer and try to connect to the computer at work by entering the work computer's IP address in the "VNC server (host display or host::port). In other words, i enter the work computer's IP in the format xxx.xxx.xx.xx into that field (nothing else). Then i click connect, and i get an error message saying "failure to connect".

As i mentioned, the computer at work is on a network, probably with a firewall, i'm not sure.

Sorry if this info is vague, but what do i need to do to get this working? Thanks for any help.

Do you have a VPN connection?

I would talk with the Network Sys Admin, to get Firewall details, and to make sure that it is ok, that you are not violating Company policy.

ok
well i'm thinking that my problem may be that there is no port open on the firewall at work. How do i go about opening a port, say 5959 or something? What kind of security implications would this result in?

xp home -- NAT/router WAN -- Internet -- WAN firewall/router -- w2k pro

you need redirect a port from the firewall office to your office computer (w2k).
well... I can't control the firewall office (because I don't have right access)!

How bypass office firewall router without right access ?
(valid for unstrong firewall content reading header packet TCP)

from...
Office computer (w2k) need a scheduled script make an outgoing connection:
"C:\Program Files\UltraVNC\winvnc.exe" -autoreconnect -connect myhome.dyndns.org::443

to...
Home computer with viewer on listen mode:
start...program... UltraVNC ... UltraVNC Viewer ... Run UltraVNC Viewer (listen mode 5500 default port)
"c:\program files\UltraVNC\vncviewer.exe" -listen 443

you need a special viewer can stop incoming reverse connection from winvnc

Home router port forwarding:

read port forwarding
https://uvnc.com/addons/routerconf.html

you need to open on your home NAT/router a port 443
port 443 = https port
(normally, you just need to activate https because already known service)

if you are not subscribed a rent public static IP at your home ,
you can subscribe to a free public static hostname known as dynamicDNS service (like dyndns, no-ip, etc.).
but needed supported by your own home NAT/router)
or
you need install client DynamicDNS on your home computer if is'nt available on your home NAT/router or you don't have a NAT/router

example: myhome.dyndns.org needed to be subscribed and saved
on your home router or on your client DynamicDNS and activ to be reachable from anywhere of the Internet

Or, you could try a circumvent solution with, 'Reverse HTTP Starter'. I use it. Works like a charm.
