Cannot Connect via DSM when Port Forwarding...

[Marko]

I've got the problem, that i cannot connect to the UVNC Server if i'm using Port forwarding and the DMS Plugin included with UVNC 1.0.1.

If I'm connecting to the regular port which is also set in the WinVNC settings (eg. 5900) it works properly, if I'm trying to connect from Internet to another port (eg. 5953) wich is Forwarded to the port 5900 the VNC Viewer keeps "Negotiating the Protocol version". And nothing happens.

I also tried this with a local port forwarder. (AnalogX) I forwarded my Port 25 to 5900 and nothing happens... If i'm using port 5900 it works...

Maybe this is a bug of the plugin or of UltraVNC itself, or I'm doing something wrong...

I already searched the forum and found some similar problems but no solution cause the problem was not reproduceable. Maybe now you can reproduce it...

Here are the 4 log files...

Marko,

Can you connect locally without the plugin? (Locally, as in over your LAN from one machine to another. If you are testing from your local machine TO the same machine you need to allow "loopback" connections or it will never work.)

Can you connect locally WITH the plugin?

Can you connect through the port without the plugin?

[lambda379]

I have the same problem. I can't connect to the UVNC server using port forwarding with the DMS plugin enabled. If I disable the plugin, I'm able to connect. I am able to connect to the server through my home network (not port forwarding) with the plugin enabled.

[scovel]

Details, details, I need details!

What OS are you connecting from/to. Got some logs? VNC and plugin logs. What's the firewall? Are there any log entries in the firewall when you are attempting the connection?

Sean

[lambda379]

Here are my details.

Windows XP Pro To and From
Linksys Router RT31P2 Firewall

The logs below were created by first the successfully connection via my home network and second the unsuccessfully try using port forwarding.

Guys,

You've got me stumped. The plugin logs look fine. I'm at a loss here. Maybe Rudi or Sam have some insight.....????

Do you have "Allow Loopback Connections" checked in the server properties?

I'll try to setup some port-forward tests when I get some time and see if I get the same results.

I have the same problem. I'm using UltraVnc in LAN using no-reg dsm and it works fine.

I wanted to use it in WAN connection, so I forwarded the port in the router, and tested it by telneting it remotely: telnet host 5800 and had no problem. However, when I try to connect, it takes a few moments and it says negotiating connection protocal before it gives the following error message:


Connection Failed - error reading protocol version

Possible causes:

-You've forgetten to select DSMPlugin and the server uses DSMPlugin
-The selected DSMPlugin is not compatible with the one running on the server
-The selected DSMPlugin is not correctly configured (also possibly on the server)
-The passwored you've possibly entered is incorrect.

I dont know what details you might need, but i made sure i select DSMPlugin no-reg on both sides, the viewer and the server.

I'm also using the same version on both sides 1.0.1 build Aug 6, 2005. And don't know why it might be incompatible.

It never prompted for password.

I'm using Windows XP Pro on both, server and viewer machines.

Thank you for the help. Please let me know if you need more details.

P.S. I tried both, with and without loop back connection enabled. It didnt make any difference that I knew of.

Sorry for bugging you guys. I found my mistake. I was supposed to open port 5900 instead of 5800 on the router. But now since I dont have access to the router, I could switch the ports on the server.
