How can I avoid tunneling when QVS is behind a firewall?

[bnichol]

I have several documents that are avaialbe on a QlikView Server (v9 SR6) in a DMZ. The logs show that all my external traffic is using tunneling, not port 4747. Port 4747 has been granted access to the users, and they have verified with telnet, that they can connect on port 4747. The users have the correct IE Plug-in installed, but performance is deadly with the tunneling.

How can I identify what is causing the tunneling?

Here are my server security settings...

Any suggestions?

Hi,

Even without tunneling performance might not be great . It depends how far, and how bad is the network connection.

Try theese:

• disable tunneling from management console
• disable tunneling from the configuration files
• delete the tunnel.dll file 🙂

I'd like to disable tunneling, but at that point some of my customers can't access their documents. I've tried this and they end up looking at a blank screen.

The users are physically less than 200 meters(yards) away, just not on an internal network.

Is there a way identify if the issue is at the server or the client end?

How about unmark "Enable server push over HTTP tunnels"? This setting is by default off?

I've had the same results if that setting is checked or not. Just tried it, to see if performance might be improved.

Hi,

Do Your external users use a Public Adress to reach the AcessPoint ?

try to change the server connections property on the menu System/Setup/YourQlikviewWebServer/AccessPoint. By default, the name is set to localhost.

Then, in the External Linking Property (System/Setup/QlikViewServer/General), write the public adress you use.

Regards.

Thanks for the suggestion. This is probably what I've been searching for.

I'll try some testing, but do you know the format for the "External Linking Property", there's no info on it in the server reference manual.

Thanks,
