Problem with REPEATER.EXE -- Double NAT?

[freedom4all]

Hello,

I have problems using repeater.exe (latest version, 1.0.4) do connect this way, client is winvnc.exe from ultravnc 1.0.1, no DSM.


VNC-Viewer
|
|
privIP
--------------
FIREWALL
--------------
fixed pubIP, NAT No.1
|

/~~~~~~\
the big, wide internet
\-----------/
|
|
fixed pubIP
-------------------
DSL Router-Firewall,
port forwarding for
5901 to the repeater.exe PC
(= NAT No.2 ??)
-------------------
|
LAN
|
~~ Repeater.exe on Win2k3-R2
|
~~ winvnc.exe on Win2ksp4
|
~~ Other Win2ksp4 workstations
.
...


Using a 3rd PC in the destination LAN I *CAN* use the repeater.exe to connet to another workstation running also winvnc.exe

Is that possible scenario I "painted" above possible? Is that counted as double-NAT; There are other postings here stating that double NAT is not supported...

The VNC viewer tells "negotiate protocol version" and hangs. While watching the repeater.exe screen (PCA ) I can see, that nothing shows up there (neither succeed nor error messages)


Any ideas ?

So it looks like a classic Repeater Mode 1 scenario, minus the port numbers in your diagram. Try to verify the port you are connecting to is correctly forwarded (according to diagram on ultravnc.com for repeater mode 1, port 5900 is default for repeater connection - so either forward publicIP_port5901 -> PrivateIP_port5900, or connect to the repeater from your viewer with port 5900 instead.

If the logs aren't showing any connections at all I'd definitely lean toward that. Sounds like a forwarding issue, especially since it seems to work fine within the destination LAN.

Hope that helps!
