connecting behind routers: what I've done wrong

[rpking]

Hi,

I am a newbie to ultravnc, and I have tried but failed to
connect two computers behind routers using repeater. I'll
describe in detail what I've done, and I would really
appreciate if someone can point out what I've done wrong.
The ip given below are just for illustration purpose; they
are not real.

Background: Want to run my office's computer as the server,
and remote control the computer from my home. I installed
ultravnc RC17, and both computers run WinXP professional.

(1) At my office:
public (external) ip: 140.190.212.121
internal ip (given by a D-Link router): 192.111.1.111
(2) At my home, I use a cable modem service, and I have a
Linksys router in my home for direct cable connection
or for wireless connection to the internet. The home
computer thus has a public ip and an internal ip
forwarded by the router.

What I've done to attempt the connection:

(A) At my office's computer, which is designated to be
the server:
(a) Run "vnc_repeater 5901" from the cmd (MSDOS) box.
The following messages appear in the cmd window;
leave the box alone as is.
UltraVnc> socket() initialized
UltraVnc> bind() succeded to port 5901
UltraVnc> listen() succeded
UltraVnc> Waiting for connection ...
(b) Start Ultr@VNC Server. In the Property tab, check
the box of "Allow Loopback Connections".

(B) At my home's computer:
(a) Start Ultr@VNC Viewer; a window pops up. In the
"VNC Server:" box near the top of the window, put in
192.111.1.111::5901
. Then, at the bottom of the window, check the
Proxy/Repeater box, and put
140.190.212.121::5900
in the next box.
(b) Click on the "Connect" bottom. Unfortunately, after
a few seconds, the message "Failed to connect to
server!" appears.

I also tried using single ":" instead of double "::" in the
above ip inputs; ip inputs without "::59xx" in both of the
boxes or in only one of the boxes; switch 5901 and 5900.
All of them are not effective.

I also tried not using the router in my home, thus directly
connecting the computer to the cable from the wall. It
didn't help the VNC connection. Is the D-Link router at my
office's end to be blamed?

Any advice will be greatly appreciated!

You need to set your linksys router to forward TCP port 5901 to your server (192.111.1.111).

Just guessing but you said you selected allow loopback but is it set in the registry correctly? I think a loopback.reg file may be in the zip.
